Summary:

Mobilizing your system on the GSSI Model 643 survey cart allows you to cover ground much more easily and conveniently than with the conventional system configuration. The cart can accommodate the 270 MHz, 400 MHz, 900 MHz, 1 GHz, 1.6 GHz, and 2.6 GHz antennas. The 643 cart incorporates a unique antenna capsule design that protects these antennas from the elements and renders the antennas weatherproof. It also incorporates a survey wheel for high-precision distance measurements.

GSSI Antenna:
GSSI Model 50400S antenna has greatly improved resolution performance over previous GSSI mid-frequency antennas, such as the Model 3105 (300 MHz). The Model 50400S can be used in continuous, survey wheel or static stacking modes. Model 50400S is a 400 MHz “smart” antenna. This antenna has a special chip in it that will work with the SIR-30 and future control units (not the SIR-3000 or SIR-20). This chip will identify the antenna to the SIR-system control unit so that the controller will be able to automatically load up the correct default settings. The 50400S will function with a SIR-3000, SIR-20 or any of GSSI’s previous controllers, but the user will need to manually set the collection parameters on the SIR-system.
