Infinity GPS-MIC-1 - Manual (Page 5)

3.0 How it works
The Infinity Model GPS-MIC-1 is a computerized handheld unit that scans the open skies
looking for 14 GPS satellites overhead. The unit “listens” to these orbiting satellites and
eliminates the weakest satellite signals. From this point the unit computes the location of
the receiver based in the relationship to the satellites being received. The unit them
computes the user’s longitude and latitude which is updated every second, computing
direction of travel, speed and altitude and shown on one main screen.
Stored in the non volatile solid state on-board memory of the unit is the information from
each update. This recording also consists of one setting waypoints, event marker points
and icons, trails and routes as well as when asked, a relationship between the user and up
to 5 or more other users selected in a group, and their relative distances and direction from
the user’s handheld unit.
By connecting a USB cable to the Infinity GPS-MIC-1 unit, one may download all the
collected data to a PC, or, transmit this data over a two way transceiver (of most any type)
to all other programmed group receiving radios as well as the main receiving point and a
PC/or laptop if connected to a radio transceiver and another Model GPS-MIC-1 unit serving
as a central controller over the air. No other interface is required.
Unlike other GPS handled stand-alone units, a built in compass is built inside the unit.
To ensure accuracy, this unit receives GPS satellite information as well as WAAS (Wide
Area Augmentation System) boosting GPS performance increasing GPS accuracy to within
7.6 meters vertically and 2-3 meters horizontally according to the FAA. The GPS-MIC-1
receiver receives the WAAS signal that is transmitted on the GPS signal.
While some remote areas do not receive WAAS signals, the GPS-MIC-1 will operate
normally using the GPS receive only portion of the satellite signal.
