Overview
The Vector Compact (n2k)™ GPS Compass is based upon Hemisphere GNSS’
exclusive Crescent® and Crescent Vector™
II
technology.
The Vector Compact (n2k) is a complete GPS compass and position system in a single
enclosure that requires a standard NMEA 2000 cable connection. With NMEA 2000
support and ease of installation, the Vector Compact (n2k) is the perfect solution for
marine-based applications.
The Vector Compact (n2k) 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 multi- path mitigation, and fewer components.
The Vector Compact (n2k)’s GPS antennas are separated by 13.5 cm between their phase
centers, resulting in better than 2° rms heading performance. The Vector Compact (n2k)
provides heading and position updates of up to 10 Hz and delivers position accuracy of
better than 1.0 m 95% of the time when using differential GPS
corrections from Space Based
Augmentation Systems (SBAS).
The Vector Compact (n2k) also features Hemisphere GNSS’ exclusive COAST™ technology
that enables SI-TEX Marine Electronics receivers to utilize old differential GPS
correction data for 40 minutes or more without significantly affecting the position
quality. The Vector Compact (n2k) is less likely to be affected by differential signal
outages due to signal blockages, weak signals, or interference when using COAST.
