GPS overview
This chapter describes the various modes of operation and features of your IsoMatch Global GPS receiv-
er and internal sensors. For your convenience, both the GPS and differential correction of the IsoMatch
Global GPS antenna are pre-configured. The receiver will work out of the box, and for most applications,
little user set up is necessary. When powered for the first time, the IsoMatch Global GPS antenna will
perform a "cold start," which involves acquiring the available GPS satellites in view and the SBAS differ-
ential service.
GPS operation
The GPS engine is always operating, regardless of the DGPS mode of operation. The following sections
describe the general operation of the IsoMatch Global GPS engine.
Automatic tracking
The GPS engine within the IsoMatch Global GPS antenna automatically searches for GPS satellites, ac-
quires the signals and manages the navigation information required for positioning and tracking. This
is a hands-free mode of operation.
Receiver performance
The IsoMatch Global GPS antenna works by finding four or more GPS satellites in the visible sky and
uses the information those satellites provide to compute an appropriate position (typically within 2-3
meters). Since there is some error in the GPS data calculations, the IsoMatch Global GPS antenna also
