"Hi
Altought 2 years has been passed. But google bring me this thread. I want to know, was you able to get sub meter accuracy in APM using GPS?
Thanks"

Sub meter accuracy for the Arducopter GPS?

I am wondering if there is a proprietary binary code output from the compatible Arduino GPS chips, or if an NMEA output is fine? This is because I want this magical GPS unit onboard:…Continue

navi gator replied to Gerard Lavoie's discussion Sub meter accuracy for the Arducopter GPS?"true, but if you had coordinates for the ground station GPS then you know how accurate one of your guns are and you adjust the other accordingly. another idea you can do some post mission processing with your data and CORS stations to get a better…"
Gerard Lavoie replied to Gerard Lavoie's discussion Sub meter accuracy for the Arducopter GPS?"At this point, I have no idea... I'm assuming the processing time to do this would not improve the accuracy, regardless of the precision you can put into the system.... It's like shooting at a moving target.. If you have a gun in each…"

"Gerard, Current hardware does not support SD cards but yes it is possible to record data to onboard "blackbox" due we have memory chip already installed and this data can be extracted later to ground station or other computer via serial…"

"sure
you can log every info the copter has to eeprom, to SD card or send it direktly to the ground"
Gerard Lavoie replied to Gerard Lavoie's discussion Sub meter accuracy for the Arducopter GPS?"I think I'll have to watch out for this if I'm using gimbals and camera mounts eh? Is there a way to use the pitch roll and yaw from the camera mount instead, and the x, y, time from the gps... and the z from say a barometric…"
ModeratorSebastian Gralla replied to Gerard Lavoie's discussion Sub meter accuracy for the Arducopter GPS?
"it gets time from gps
roll, pitch and yaw does it have
altitude from gps and baro
-> yes you could make it do that for you ;)"
Gerard Lavoie replied to Gerard Lavoie's discussion Sub meter accuracy for the Arducopter GPS?"I need to output to an ascii file to be used for stereosopic viewing. You are right... I am in R&D so I got a bit excited late last night about seeing the "sub-meter accuracy" SXBlue system. The more I have read into it the more I…"
JDronesJani Hirvinen replied to Gerard Lavoie's discussion Sub meter accuracy for the Arducopter GPS?
"Gerard, also what are you trying to achieve with this sub meter accuracy? General accuracy also varies a lot on different areas. If you plan to have position hold for quad less than 1 meter on X/Y plane.. Hmm i'm afraid that it's more or…"
Gerard Lavoie replied to Gerard Lavoie's discussion Sub meter accuracy for the Arducopter GPS?"Thanks for that Peter.
So, no go on better accuracy? Is this unit a waste of cash for Arducopter considering the price difference between it ($1650)
Can the on-board GPS in say the Arducopter be used as rover with say a vehicle antenna as a base…"
Patrick Hammer replied to Gerard Lavoie's discussion Sub meter accuracy for the Arducopter GPS?"Gerard
If you read the notes at the end of all the marketing blurb - and it becomes clear that the sub-meter accuracy referred to is subject to certain conditions - as it is with most modern day GPS modules with half decent firmware and onboard…"
Gerard Lavoie replied to Gerard Lavoie's discussion Sub meter accuracy for the Arducopter GPS?"I think you should send me a sample of the current output log, using Windows Hyper-terminal. It would be a start. I think that reading a standard NMEA output (>1Hz) is a good idea here, if it isn't already the case. I should look at the log,…"
