Integrating GSP-1620 Modems into OEM Products

Calculating Antenna Cable Length

The maximum loss for an antenna cable of any length is 0.6 dB at 1.6 GHz for modem transmit and 3 dB at 2.5 GHz for modem receive.

You must take these losses into account when calculating antenna lengths for a GSP-1620 modem installation. For example, the GSP-1620 Modem Integrator’s Kit utilizes three feet of LMR 195 cable, which has a loss of 0.6 dB at 1.6 GHz.

Mounting Antennas at the Field Site

When mounting an antenna on-site, you must position it properly to obtain Globalstar satellite signals. You can mount the antenna on a flat surface or on a pole. In either case, you should seal the antenna connectors against dirt and moisture.

Caution

The ODU antenna must be installed in a configuration that ensures a

minimum line-of-sight separation distance of 21.5 centimeters (8.5

 

 

inches) is maintained at all times between the ODU antenna and any

 

personnel.

Finding a Good Antenna Location

When installed in the field, the antenna of a GSP-1620 modem product must have a direct line of sight to the Globalstar satellites. Keep in mind that Globalstar satellites follow different paths across the sky, and you cannot predict where they will be.

Position the DRA antenna outdoors where it has a clear view of the sky, unimpeded by tall obstacles such as buildings and trees.

Signal fading associated with trees, buildings, and other obstacles that prevent a clear line-of-sight to the satellite can cause degraded operation in a mobile environment.
