Accord Technology Completes Full Suite Advanced GPS for Aviation

Accord Technology LLC was recently authorized TSO-C145c for its latest receiver/sensor in the NextNav product family, the NextNav MAX GPS WAAS Class Beta-1, -2, -3. This successful GPS development is a key solution in a series of Accord Technology’s affordable civil aviation GPS receivers and sensor, the company said.

Available as circuit card receivers (CCA) for avionics OEM hosting or as line replaceable sensor units (LRU) for aircraft installations, MAX is affordable and meets the latest standards, worldwide. It supports ADS-B (Automatic Dependent Surveillance-broadcast), all normal GPS procedures, as well as precision approach requirements such as LPV (Localizer Performance with Vertical Guidance) and RNP AR (Required Navigation Performance with Authorization Required).

The NextNav MAX GPS technology is the most advanced in the world and is compatible with Satellite Based Augmentation System (SBAS) solutions such as the United States’ WAAS, the European EGNOS, Japan’s MTSAT, and GAGAN in India.

“This TSO authorization for the NextNav MAX gives us greater flexibility to serve our customers with WAAS Beta 1 Only or Beta 1, 2, 3 LRU’s and CCA’s to fit their need,” commented Hal Adams, chief operating officer for Accord Technology. “The NextNav MAX is another important first for Accord Technology and we are anxious to move forward now with our AC 20-165 approved GPS sensor,” added Adams.

Accord Technology received TSO-C145c for its NextNav mini in 2010. The NexNav mini GPS technology was the first GPS WAAS sensor to be authorized by the Federal Aviation Administration TSO-C145c WAAS Class Beta-1 Only. The NexNav mini solution is a market-breaking hybrid of automotive technology and aviation requirements providing an affordable solution for ADS-B GPS source.

NextNav MAX’s DO-229D compliant aerospace GPS-SBAS receiver is certified by the FAA for TSO-C145c Class Beta-3 operation and is the enabling technology for several key applications, including:

• Primary means of navigation
• Localizer Precision with Vertical guidance approaches (LPV)
• Airborne spacing assurance
• Airborne Collision Avoidance (Non-TCAS System)
• Constant descent approaches
• Surface area movement management
• Current and advanced Terrain Avoidance Warning System (TAWS)
• Advanced Air Traffic Management (ATM)
• Required Navigation Performance enhancements (RNP AR)

“Whether it’s a need for LP/LPV approach precision or highly reliable PVT, NextNav MAX offers standard and custom solutions according to what our customers need,” Adams said. Designed around a small form-factor, the NextNav MAX CCA is delivered ready to integrate into host avionics systems, an LRU sensor or as a standalone module to ARINC 743 requirements. “We can even package the CCA in a module, tailored to your application,” Adams said.
