Hi. I am on a rocket team, and we participated in the Teknofest rocket competition in Turkey. Our rocket reached a speed of Mach 1.3. While the rocket was ascending, the number of satellites in use dropped to 1 from an initial count of 10. Is there any limitation at high speeds to prevent these systems from being used in military applications? Thanks.

Limitation was introduced by Coordinating Committee for Multilateral Export Controls …(COCOM)
Maximum Altitude 18000 m
Maximum Velocity 500 m/s
Maximum Acceleration 4 G

for commercial chips

Our rocket reaches up to 13G so may you advice any GNSS module?

Authorization to use military technology must be obtained…in Europe Septentrio AsteRx-m m(special military firmware) and Phoenix-S GPS receiver from DLR produces something similar but the monopoly is in the hands of the us defence.
