Live vehicle geolocation, taken from the on-board Icomera WiFi system.
npm install live-icomera-position
Usage:
live-icomera-postion
Options:
--interval <ms> -i <ms> How often to fetch the current position.
Default: 3000
--timeout <ms> -t <ms> How long to wait when fetching a position.
Default: 2500
Examples:
live-icomera-postion -i 5000 >>positions.ndjson
asStream()
returns a readable stream in object mode.
import {pipeline} from 'node:stream/promises'
import {asStream} from 'live-icomera-position'
import ndjson from 'ndjson'
await pipeline(
asStream(),
ndjson.stringify(),
process.stdout,
)
An individual data point will look like this:
{
latitude: 50.9069,
longitude: 7.0649,
altitude: 36.9,
speed: 97, // km/h
nrOfSatellites: 8,
mode: '3' // see below
}
You can also use the EventEmitter
-based API:
import {asEventEmitter} from 'live-icomera-position'
const positions = asEventEmitter()
positions.on('error', console.error)
positions.on('data', data => console.log(data))
The mode value in a datapoint appears familiar with the one a widespread gps client called GPSD uses. We don't have any confirmation that the icomera system uses GPSD, but if it did the mode values would mean following: | Value | State |
---|---|---|
0 | no value seen. | |
1 | no position. | |
2 | 2D position, no altitude. | |
3 | 3D position, altitude present. |
