Vibration (Random Profile)
The GSR2600 can acquire and track satellites while undergoing vibration levels
as shown below. It assumes that C/No > 45 dB-Hz and that the GSR2600 is in
high-dynamics mode. Assuming appropriate mounting, the GSR2600 conforms
to random vibration templates for RTCA/DO-160C, Section 8.6.2 (Curve C
template), MIL-STD-202F, Test Condition I (Letter A nominal template), and
ASAE EP455, Section 5.15.1 nominal template.
