VS131 sub meter beacon compass

Product Details

Hemisphere VS131

Product Description

By integrating L-band technology into Vector ™ In the VS family of products, Vector VS131 is required for precision marine and land applications ™ The excellent directional and positioning performance of the receiver makes Vector VS131 an ideal choice for professional mechanical control and navigation applications within the L-band service area

Vector VS131 uses Hemisphere GPS' Crescent ' ® Vector's patented technology brings a brand new user experience in undulations, pitch, roll, and even stronger positioning performance.

Vector VS131Key advantages of the receiver:

Support L-band
Professional directional accuracy<0.03 ° rms
Differential positioning accuracy<30 cm rms
Fluctuations<30 cm rms
Pitch and roll<1 ° rms
Concise menu operation
Continuous accurate orientation for 3 minutes in case of unexpected GPS interruption
COAST technology can maintain differential positioning accuracy for 40 minutes or even longer in the absence of differential signals
Integrated gyroscope and tilt sensor can improve fast start-up time and provide heading update information in case of temporary loss of GPS signal

remarks
remarks	① Depends on the number of visible satellites, geometric distribution of satellites, baseline length (for local services only), and ionospheric activity in a multipath environment; ② Depending on the number of visible satellites and their geometric distribution in a multipath environment; ③ Hemisphere GPS patent; ④ Under static measurement conditions; ⑤ When the product is placed nearby with a turning magnetic compass, this is the minimum safe measurement distance. The ISO 694 standard defines "nearby" as a separation distance of 5 meters (16.4 feet) relative to the compass; ⑥ Based on a 40 second time constant; ⑦ Authorization needs to be obtained from OmniSTAR;
