Add support for operating Unicore modules (e.g., UM980).

[geofis]

My apologies in advance if some of these issues have already been discussed in the repo's issues or feature requests. Likewise, I want to congratulate @Stefal and the other contributors to rtkbase. This software is, for me, a great example of what can be achieved by joining forces to achieve "Accuracy for the Masses."

Unicore Communications GNSS modules seem to have been groundbreaking in 2022-2023. Specifically, the UM980 module is a triple-frequency receiver with 1408 channels. Other modules, such as the UM982 (dual antenna for heading) and the UM981, have similar features. Although their RTK solution algorithm (based on the GNSS SoC-Nebulas IV) is good, it seems that the ZED-F9P outperforms it. But the ability of the UM980 to observe multiple frequencies and track various signals is unparalleled in terms of cost-effectiveness. Many electronics retailers are assembling boards with this module (many in China, but also SparkFun, GNSS store, among others). In fact, as far as I know, some or many of the GEODNet bases use the UM980.

In the notifications I receive from rtkbase, I read that there are plans to support Septentrio modules, so it might be interesting to consider these modules as well. If the decision is made to expand support to Unicore, I can help (with my basic knowledge) in this regard. I have conducted some experiments with the UM980, and it seems to have great potential. On the other hand, rtkbase is a great piece of software, and Unicore receivers can make a good pair with it.

Recently, I finished assembling a DIY receiver based on the UM980. Specifically, I built a receiver ready to be used in the field: waterproof, with a long-lasting battery, charged with a solar panel, etc. I posted a sneak peek of the receiver capabilities here and here. I intend to use this receiver as a moving base since, as a rover, it does not outperform the ZED-F9P in obtaining RTK-fix solutions. Since I have already built several receivers based on the ZED-F9P, constructing one based on the UM980 wasn't challenging for me. However, the software part required a specific solution, and that's why I thought of using rtkbase for it. The software part needed a specific solution, and that's why I thought of rtkbase for it.

I started my solution as something personal and slightly hardcoded, which I placed in my rtkbase fork (https://github.com/geofis/rtkbase) in the "unicore" branch. The development I did consists basically of the following. The main service, when started, configures the receiver using a command file (.cmd file) to make it work primarily as a base for obtaining coordinates and date/time and to collect raw observations in a file. The command file configures the module to transmit RTCM3 messages from COM1 (UM980 has 3 COM ports), specifically MSM messages, as well as navigation messages from each constellation (excluding position and/or antenna messages). This way, the main service sends RTCM3 messages to the preferred TCP port, although I chose 5015 (default) to not break the dependency on gpsd/chrony (see more below). UM980's COM1 is connected to the Raspberry's USB port through an FTDI, so you need to use something like "ttyUSB0" in the rtkbase main service. Additionally, the output format must be configured as rtcm3 in the main service. I added the -b flag to str2str to be able to relay back with the module and send it commands, although this undoubtedly poses vulnerabilities.

On the other hand, the command file also configures the module to transmit the NMEA GPRMC message through COM1. This is useful for fixing the system time with gpsd/chrony, very useful in my case, as I will use this equipment as a mobile base where internet connectivity could be null.

Finally, the command file configures the module to transmit raw observations through COM2 (connected to the Raspberry's UART, "ttyS0"), to be used by the file-saving service. This is the main difference from the original rtkbase, because in this case raw observations come out through another port and cannot be collected from TCP to create the file of raw observations. However, I am convinced that the ideal solution would be to send messages in Unicore's native format to TCP so that rtkbase could process the streaming with rtkrcv and generate a PPP solution (just as it does with U-Blox). Still, RTKLIB (the original and demo5) does not recognize the Unicore format. The files generated by Unicore modules can be in two types, ASCII or binary, and are converted to RINEX with a Unicore tool called "Converter" (only for Windows, but it works with Wine from Linux as well).

Although Unicore Communications support does not compare to U-Blox's, the module is extremely cheap for all it offers. Finally, I reiterate that I am willing to support a functionality for rtkbase. I am not an expert in Flask, although I understand it, but I offer my support as far as my knowledge reaches.

José.

I also think it would be great if an inexpensive receiver like the one from Unicore could be used for a base station. I own a UM982 and use it to steer my tractor. There is a discussion thread: https://discourse.agopengps.com/t/is-the-um982-an-f9p-killer-for-aog/13960/250 There is also a Telegram group that deals with the base station: (https://t.me/Centipede_RTK) Your knowledge could be helpful

[geofis]

Hi @tomischmid,

Thank you for sharing your experiences! I've browsed through the discussion thread and found the insights interesting, even though my primary focus is on ground deformation monitoring. I will create an account on the Discourse group soon to continue following the discussions more closely. Regarding the Telegram group, while I'm not a user of the platform, I'm certainly interested in any significant developments or insights shared there that could be relevant to regarding the use of Unicore modules.

The updates that often come from China are incredibly fast and unexpected. Recently, I noticed that one of the brands manufacturing hardware compatible with Meshtastic (an off-grid LoRa network) has included a dual-frequency chip at nearly cost price (I estimated the chip costs around 3 dollars). It's not designed for use as a base station, but it certainly astonishes with its vast capabilities and low prices.

[Stefal]

To add the full support for a Gnss receiver inside RTKBase we need two things:

• A way to detect and configure the receiver
• Raw messages support in RTKLib

As long as RTKLib doesn't support the UM980 binary messages, I can't do anything. Right now we can only use it configured to output rtcm3 messages, as you already did.

[geofis]

Hi @Stefal

Thank you for outlining the requirements for integrating a GNSS receiver into RTKBase. I understand the limitations regarding RTKLib's current lack of support for UM980 binary messages. However, this may soon change because there are libraries, such as those from SparkFun, that do support Unicore's binary format. In the meantime, I also wonder about the feasibility of supporting Unicore receivers through RTCM messages, since "at least for me" this is already operational. This could be a viable interim solution until native support is possible.

Regarding the detection and configuration of the receiver, I agree this is a challenging aspect, especially considering UART connections for end-users and lifespan of development boards. Perhaps a model from gnss.store might offer a way forward, since they attach a USB via the I2C port. However, there remains a significant hurdle: manufacturers of UM9* development boards do not provide information on the lifespan of their boards. This lack of transparency could pose issues for long-term support and reliability.

I look forward to exploring these possibilities further and contributing to RTKBase's growth and adaptability.

Oops, sorry, I didn't initially intend to share the executable as I was unsure about the legal implications.

However, I'm sharing it now - a version of Converter that appears to be from June 2023.

Additionally, for what it's worth, I'm also including the most recent firmware I have for the UM980.

[messplay]

Greetings, thank you in advance for such a quick collaboration, I take this opportunity to consult you since you have more experience in the UM980, does this module have the option of changing the Datum (just like the zed-f9p has) or does it always work in wgs-84?

[EliuPineda]

Hi @messplay check this reference commands manual, I found it is posible, search for "datum code". @geofis can correct me if I am lost. unicore-reference-commands-manual-for-n4-high-precision-products-v2-en-r1.2.pdf

[geofis]

Thank you @EliuPineda and @messplay for your posts. As @EliuPineda mentioned, it is indeed possible to use a "different Datum" in the UM980. If I remember correctly, for the ZED-F9P, under the DAT (Datum) option, it's possible to configure datum using various possible parameters, or by using a list of several Datums available. This seems equivalent in the UM980 with GPDTM.

My experience has been quite limited in this regard with the UM980, and it seems that in this receiver, IHO codes are used for datum, or offsets are applied.

However, I think it's preferable to perform these types of transformations in post-processing, mainly because it allows for more parameters to be defined and the epoch to be introduced (e.g. using HTDP https://www.ngs.noaa.gov/cgi-bin/HTDP/htdp.prl?f1=4&f2=1).

[messplay]

Greetings friends, here I am asking more questions, first of all thank you all, you have been really helpful, I hope in time to be able to return the courtesy. Moving on, my question is:

1. What ASCII or Binary (raw) messages should an application record so that they can later be converted to Rinex using the Unicore application?

[EliuPineda]

There is a command that is not specified in docs but works and you can use, is RANGEA COM1 1 for ASCII and RANGEB COM1 1 for binary, when I started to use UM980 I used OBSVM but did not work, even I have a script in which I am working on python to convert the observations to Rinex in real time. Please @geofis correct me if I am lost, I believe @geofis knows more than me, but I like respond questions about I know :)

[geofis]

Hello @messplay, @EliuPineda,

As @EliuPineda pointed out, the commands RANGEA COMX 1 (the "A" for ASCII, X being the chosen COM port) and RANGEB COMX 1 (the "B" for binary) could be used for capturing observables (in this example, at sampling rates of 1 second). Logically, binary files are smaller than ASCII ones, but ASCII files are more easily interpretable by high-level parsers. In addition to these, there is also RANGECMPB COMX 1, which offers a more compressed binary format, but I don't prefer it for long-term data storage (I'll explain more below).

Now, referring to OBSVM*. The command OBSVM[A,B] COMX 1 (again, with "A" for ASCII and "B" for binary) would also do the job of collecting observables, in an uncompressed Unicore format. There is also OBSVMCMP[A,B].

The most significant differences I've found between OBSVM and RANGE are:

• The messages collected with RANGEB and RANGECMPB can be parsed as a .gps file format of Novatel (is the UM980 a clone of Novatel just in a different packaging?). A very important detail that might be useful for you @EliuPineda: if you need to track observables in real time with RTKLib (e.g., demo5 from @rtklibexplorer), just configure RANGEB or RANGECMPB output messages and specify the #nov format in the str2str command formation. If you need to use convbin, just specify the input format with the -r nov flag, or simply rename the file to a .gps extension. Also, keep in mind that Sparkfun has a C++ parser that might be useful for you @EliuPineda, in case you want to check it out. The capability of the RANGEB command to deliver messages that can be parsed in real-time using str2str presents a significant advantage, offering potential for seamless integration with @Stefal's rtkbase.

• RANGEB (not RANGECMPB, at least in my tests) allows separation between multiple signals (both in L2 and L1, specifically L1C, not just L1C/A). This might be relevant in geodesy for the future, and this is why I prefer RANGEB over RANGECMPB for storing data, but I'm not absolutely sure of this advantage btw.

All the above messages can be converted to RINEX using the converter tool (the RANGECMPB require marking Rangecmp>Range tick in converter).

Finally, ephemerides cannot be collected with a single command, but must be selected by constellation. This I find to be a good feature, as it allows for easy separation of one from another. For this, you can use the commands *EPHB COMX 30, and thus collect them in binary format every 30 seconds. The converter tool will process them correctly.

Unfortunately and inexplicably, as @EliuPineda correctly notes, the RANGE log command family does not appear in the NebulasIV command guide, but they are in the Novatel guides. The fact that they do not appear in the NebulasIV guides does cause me some confusion, but as far as I have seen, the messages generated by RANGE and OBSVM* are similar.

I created example files in passive collections with an antenna placed in a window, all of 90 seconds, testing different log commands: OBSVMA, OBSVMB, RANGEA, RANGEB, RANGECMP. They are hosted here:

obsvma.log obsvmb.log rangea.log rangeb.log rangecmpb.log

I hope this info is a help to you and anyone else working with these powerful and cheap Unicore modules.

[messplay]

You people are simply amazing.

[Jef239]

I intend to use this receiver as a moving base since, as a rover, it does not outperform the ZED-F9P in obtaining RTK-fix solutions.

It's not true for forest!

[Jef239]

• Raw messages support in RTKLib

For what?

I made support for UM980 (ELT0229) and UM982 (ELT0219) in UM980_RPI_Hat_RtkBase

I use original RtkBase 2.5.0 and make some changes

• UnicoreSettings.sh fill settings.conf
• run_cast.sh execute UnicoreSetBasePos.sh for setting precise position into receiver
• run_cast.sh also can start TCP-server instead of NTRIP-server for rtkdirect
• detect and configure in the procedure configure receiver in install_script.sh
• NmeaConf - program for Unicore and ByNav configuration
• UM980_RTCM3_OUT.txt - configuration for UM980
• UM982_RTCM3_OUT.txt - configuration for UM982

PPP is work!

Limitation:

• only 115200 yet
• only RPI
• button "Detect/configure" don't work yet
• base coordinates cannot be kilometers away from the real ones

It's interesting for you?

[geofis]

I concur with @Jef239. I've recently conducted tests to achieve kinematic positioning using a UM980 as a base and two rovers, another UM980 and a ZED-F9P. For this setup, I mounted two antennas on the roof of a car: one for the UM980 (link to antenna) and the other (ANN-MB) for the ZED-F9P. I opted not to use an antenna splitter to prevent potential damage to the receivers. The testing context was predominantly open fields (usually agricultural areas) and occasionally under forest canopy, but not urban environments. The RTK-fix proportions for the UM980 were consistently higher than those for the ZED-F9P. Impressively, I achieved over 70% fixed solutions in RTK (even considering limited connectivity at times) and incredibly, up to 86% in PPK, even at distances exceeding 25 km from the base. In contrast, the ZED-F9P only reached up to 50% in RTK and no more than 70% in PPK. The use of L1+L2+L5 frequencies is simply unmatched, which is why I think the UM980 outperforms the ZED-F9P.

However, I've observed certain scenarios, like urban canyons, where the ZED-F9P seems to surpass the UM980. This might be addressed in the UM980 by reducing the solution's reliability (e.g., adjusting the CONFIG RTK RELIABILITY setting). Nevertheless, I want to make it clear that, especially in non-urban settings and with default configurations, the UM980 is superior.

I hope to find time in the future to publish the results and comparisons of my tests in this same issue. As a preview, I can unequivocally say that the performance of the UM980 is truly impressive, decisively outshining the ZED-F9P. These are the results of the PPK processing for the ZED-F9P and the UM980:

ZED-F9P

UM980

[Jef239]

The use of L1+L2+L5 frequencies is simply unmatched, which is why I think the UM980 outperforms the ZED-F9P.

This is not the only reason. And perhaps not even the main one. Unicore has less quartz oscillator noise and less code and phase noise.

However, I've observed certain scenarios, like urban canyons, where the ZED-F9P seems to surpass the UM980.

Urban canyons, winter ByNav m20 Float=104 ByNav m21 Fix=103 Float=1 Unicore um980 Fix=93 Float=1 DGNSS=10 Ublox f9p Fix=90 Float=14

There is multipath in the urban canyon. And it is changing quickly. To catch slips in such conditions, you need an INS into receiver. Therefore, Bynav M21 wins. And UM981 should also win.

[Jef239]

I made support for UM980 (ELT0229) and UM982 (ELT0219) in UM980_RPI_Hat_RtkBase

Now i release version 1.0.1

Limitation:

• only Raspberry PI
• base coordinates can not be kilometers away from the real ones

All other work well.

@Stefal, you can copy my code in main RtkBase.

Hello Jeff, if you are right, I have already corrected the post (thank you), it is indeed RANGEB, in that case I only have to include RECTIMEB in the port and would the time be recorded for the rinex file?

[Jef239]

in that case I only have to include RECTIMEB in the port and would the time be recorded for the rinex file?

I don't know exactly, but RECTIMEB includes information about day. If I wrote a converter, I would use RECTIMEB. So, you can try :-)

P.S. BTW, I wrote my own converter in RINEX, but it is not for Unicore.

It was from an incomplete install due to bad WiFi signal. Reinstall with better WiFi and now working.

Since there is no mention of UM98x in 2.6.0 release note, I still need @ Jef239 installation script for my station. @Jef239 How do I upgrade to use RTKbase 2.6.0? Thanks.

Now i am released version 1.6..0 in UM980_RPI_Hat_RtkBase (based on RtkBase 2.6.0)
