being compatible for differential and RTK operation with any other receiver that
implements the RTCM standard.
Functional Description
The sensor is activated when power is applied to either of the two power connectors,
and the power pushbutton is pushed to ON. After self test, the sensor initializes its 12
channels and begins searching for all satellites (SVs or Space Vehicles) within the
field of view of the antenna.
The sensor can track all Block I and Block II GPS SVs. All 32 PRN numbers as
specified in Navstar GPS Space Segment/Navigation User Interfaces, ICD-GPS-200,
Revision B are coded inside the sensor/processor card. As the sensor acquires (locks
onto) each SV, it notes the time and then collects the ephemeris data about the orbit
of that SV, and almanac data about the orbits of all the SVs in the constellation.
The sensor features 12-parallel channel/12-SV all-in-view operation; each of up to 12
visible SVs can be assigned to a channel and then continuously tracked. Each SV
