Chapter 1: Introduction
Overview
The V102™ GPS Compass is based upon Hemisphere GPS’ exclusive
Crescent
®
and Crescent Vector™
II
technology.
The V102 is a complete GPS compass and positioning system in a single
enclosure that requires only one power/data cable connection. With its CAN
support and ease of installation, the V102 is the perfect solution for both
marine and land-based applications such as mine construction, earthworks
and machine guidance.
The V102 is an integrated system that houses the following:
•
Crescent and Crescent Vector
II
technology
•
Dual integrated GPS antennas
•
Power supply
•
Single axis gyro
•
Tilt sensor on each axis (X and Y axes)
The gyro and tilt sensors are present to improve system performance and to
provide backup heading information in the event that a GPS heading is not
available due to signal blockage.
Crescent Vector
II
technology supports multiple RF front ends - enabling
tighter coupling of measurements from separate antennas for use in
heading-based products. Users will achieve excellent accuracy and stability
due to Crescent’s more accurate code phase measurements, improved
multipath mitigation, and fewer components.
The V102’s GPS antennas are separated by 27.5 cm between their phase
centers, resulting in better than 0.75° rms heading performance. The V102
provides heading and positioning updates of up to 20 Hz and delivers
positioning accuracy of better than 1.0 m 95% of the time when using
differential GPS corrections from Space Based Augmentation Systems
(SBAS).
The V102 also features Hemisphere GPS’ exclusive COAST™ technology that
enables Hemisphere GPS receivers to utilize old differential GPS correction
data for 40 minutes or more without significantly affecting the positioning
