SmartTrack
Advanced GPS
measurement technology | Time to acquire all satellites after switching on: typically 30 sec.
Re-acquisition after loss of lock: typically within 1 sec.
High sensitivity: acquires more than 99 % of possible observations above 10 degrees elevation. Low signal noise. Robust
tracking. Tracks weak signals to low elevations. Multipath mitigation. Jamming resistant.
