Improving GNSS Attitude Determination

This article describes an integration of a single-frequency GNSS, two-antenna heading system with low-cost inertial and magnetic field sensors in order to improve the availability and reliability of pure GNSS attitude determination. This method calculates a redundant attitude solution in an error-state Kalman filter using different sensor setups. As a result, the process of carrier phase ambiguity resolution accelerates.

Indoor Location: To Boldly Go . . . with or without GNSS

A cross-industry group comprising 22 companies has launched the In-Location Alliance to drive technology innovation and market adoption of high-accuracy indoor positioning solutions such as Bluetooth 4.0 and WiFi in environments where GNSS has difficulty providing service.

Established August 23, alliance members include leading handset manufacturers Nokia and Samsung as well as chipset providers, among them GNSS and mixed-signal RF companies Qualcomm, CSR (most of whose assets were recently acquired by Samsung), and Broadcom.

Trimble Launches AP20-C GNSS Inertial OEM Module MEMS Sensors

Trimble AP20-C GNSS/inertial OEM board with MEMS sensors

Trimble introduced its AP20-C, the latest addition to its AP Series of embedded GNSS-inertial OEM boards, at AUVSI’s Unmanned Systems North America 2012 Conference and Exhibition today (August 7, 2012).

Incorporating a compact, custom-built inertial measurement unit (IMU) based on commercial micro-electromechanical mechnical system (MEMS) sensors, the AP20-C enables system integrators to achieve high-rate position and orientation measurements with exceptional accuracy, according to the company.
