Topcon’s GMS-2 features standard WAAS or EGNOS positional correction augmentation. These satellite based signals provide extensive coverage throughout the US and Europe respectively and provide the GMS-2 with “off-the-shelf” real-time sub-meter signal correction. However WAAS and EGNOS satellite signals can be limited at times, making them susceptible to sporadic or blocked signal reception in shrouded areas such as tree canopies, around tall buildings, or near other large obstructions. Now there’s an alternative - Topcon’s wireless BR-1. The BR-1 provides access to free radio-based, real-time Coast Guard Beacon correction signals that feature less potential for interference and blockage. The BR-1 has four tracking channels allowing it to monitor simultaneous beacon signals and choose/update the best correction available.

For over 10 years Coast Guard Beacon signals have been providing reliable, real-time data to improve positional accuracies for coastal and inland waterway navigation across the US and Canada. Widely accessible throughout North America, these signals can be used as a viable alternative to WAAS correction signals for data collection, navigation, and other field applications. The advantage? Coast Guard Beacon signals are land-based terrestrial radio signals, much less susceptible to interference and blockage, making them the perfect correction signal alternative for your GMS-2.

BR-1 features:

• Reliable source of real-time corrections for GMS-2
  

• Lightweight, compact and easy-to-use
  

• 4 Beacon tracking channels
  

• Bluetooth Wireless Communication
  

• 1 meter drop warranty
  

• IP66 Rugged for rough field use

Adding a BR-1 to your GMS-2 receiver couldn’t be easier. Integrated Bluetooth® wireless communication means no cables or connectors! The wireless BR-1 integrates an internal li-ion battery that provides 15 hours of continuous field use, and is user replaceable and rechargeable. The included protective soft case lets you carry the BR-1 on your belt or backpack strap, and features a clear acrylic window allowing for at-a-glance signal reception/GMS-2 communication verification. Color LED’s indicate Blutooth wireless connection status, battery status, and beacon signal reception. There’s even a serial port for flexibility to connect to other GPS receivers or to a PC for firmware updates.

Whether you find yourself out of range of WAAS or EGNOS signals on a regular basis, experience weak or intermittent correction signals, or you’re just looking for an alternative to help streamline work flow and eliminate post-processing back in the office, Topcon’s new BR-1 Beacon receiver is your answer.
