„ Integrated GPS and L-Band Antenna
The all-in-one housing incorporates our compact GPS
antenna with excellent tracking performance and a
stable phase center for GPS L1 and L2. The robust
assembly features a standard 5/8” BSW thread for
mounting directly to a surveyor’s pole, tripod, or mast.
„ Communications
The SF-2040 provides two 7-pin female LEMO
connector communication ports, labeled COM1 and
COM2, located at the bottom front of the sensor (as
shown in Figure 1). Each conforms to the EIA RS232
standard with data rates from 1.2 to 115.2kbps.
COM1 is the control port, and COM2 is the data port
(see Figure 4 for a schematic of the LAND-PAK
interfacing).
