Hello everybody to this fine forum and sorry for my bad english.
I have bought the above Sanav GPS module for my UAV quadrotor project, but i noticed that when i moved 5-10 meters horizontaly nothing changed at the lat/long/altitude indications. This test made in clear sky with 8-9 sattelites, 3D fix, and good signal.
While i was going with my car the indications was running. This is very bad for UAV application.
Has anyone tested the above receiver (or even Etek EB-85A)?
If this receiver is not ok have you to suggest me any GPS that when you move 1 meter to show that you have moved 1 meter horizontal or/and vertical (even inaccurate), like my old Carcomm bluetooth GPS receiver which was instantly (atfer 1 second change the indications even if i was moving for centimeters). EM-406 maybe?
Before i bought it i had read the best words for this module on internet (fast 5Hz, accurate, sensitive) and now i m dissapointed...
Please help me , this is my second GPS module after GPS-41M which was not working.
