LEA-4A, LEA-4H, LEA-4M, LEA-4P, LEA-4R, LEA-4S, LEA-4T - Data Sheet
GPS.G4-MS4-06143-1
Depends on accuracy of correction data of DGPS or SBAS service
CEP = Circular Error Probability: The radius of a horizontal circle, centered at the antenna’s true position, containing 50% of the fixes.
SEP = Spherical Error Probability. The radius of the sphere, centered at the true position, contains 50% of the fixes.
The different start-up modes like cold, warm and hot start are described in the ANTARIS
Measured with good visibility and -125 dBm signal strength
Demonstrated with a good active antenna
Quantization error information can be used to compensate the granularity related error of the time pulse signal
