B20 DGPS

KEY FEATURES
  • NO REGIONAL LIMITATION

    Embedded satellite L-Band and coastal radio beacon receiver

  • INTEROPERABILITY

    Standard NMEA 0183 output format

  • COMPACT AND RUGGED

    Small, lightweight and rugged design for demanding environment

The CHC B20 is a flexible multi-purpose GPS sensor especially designed to perfectly match your positioning requirements and applications. Its embedded radio beacon and L-Band demodulators provides high precision real results without any regional limitation.

Performances

The B20 offers reliable sub-meter real-time positioning performances, fast data output rates (1Hz to 20Hz) and provides 1 PPS output for synchronization with other sensors or navigation software.

Flexible and easy to operate

The B20 can be easily installed on survey vessels for coastal works, offshore survey or navigation. Setting up of the receiver is made simple by the Windows® based configuration software. Corrections sources selection are available from the control panel which also provides satellite and differential data status.

Compatibility

Easy to connect to various external equipment such as navigation software, radar, echo sounder, the B20 conforms with the standard NMEA 0183 output format.

Competitive and Reliable

The B20 is the multi-purpose sensor to fulfil GPS differential positioning and surveying using either one or both satellite .L-Band and radio beacon corrections.
