No GPS Data

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Fly aircraft in Manual or Fly By Wire A Mode with logging of GPS data active.
2.Download logged data.
3.Observe GPS data record.

What is the expected output? What do you see instead? I expect to see GPS 
position data recorded in the log.  Instead the GPS data fields are all zero. 
The MediaTEk receiver has a solid blue light and when I run the GPS Test using 
the CLI I get good GPS data (with the exception of the num satellites field 
which always reports zero).  I updated my MediaTek firmware a few weeks ago in 
an effort to fix this problem.  By the way, GPS data also does not show up in 
the telemetry data stream when I set the telemetry format to human-readable 
Legacy format.  Perhaps if you are not flying in a guided mode the GPS data is 
not read from the receiver?

What version of the product are you using? On what operating system? Latest 
version on XP, but I have had this problem with every version that I have tried 
for the past two months.

Please provide any additional information below.

Unfortunately, I never use the data logger.  I'll have to see if others can 
address this one.

And the GPS data is also not getting output in the telemetry stream, so I 
suspect that the my GPS receiver is not interfacing with the code correctly.  
My attempts to use Fly By Wire B and RTL modes were complete disasters, and I 
am wondering if it is because of a lack of GPS data.

This problem has been solved.  I found the tip in the APM Manual about the need 
to reset the board after the GPS receiver has achieved lock.  So I guess the 
real bug is to eliminate the need for a board reset.

Ah yes, I've had this problem also.  Reset after acquisition works for now, 
we'll try to address it in the future.
