The Boeing Company initiated the Unmanned Little Bird (ULB) program in the fall of 2003 to create a developmental platform for an optionally manned, vertical takeoff and landing (VTOL) unmanned aerial vehicle (UAV). Initial flight test activity employed a modified MD530FF helicopter, with the first flight taking place on September 8, 2004. Six weeks later the program achieved a fully autonomous multiple waypoint demonstration flight from takeoff through landing.

NovAtel Offers MEMS IMU for GNSS SPAN Integration

ADIS-16488 from Analog Devices

NovAtel Inc., has announced the addition of a new commercially exportable MEMS IMU (microelectromechanical inertial measurement unit) to its line of SPAN GNSS/INS products.

Available for immediate shipping, the MEMS IMU is supplied by Analog Devices (Norwood, Massachusetts) and is exclusive to NovAtel. It can be paired with an OEM6 receiver card to provide continuously available position, velocity, and attitude (roll, pitch, yaw) in a small, single-unit form factor.

GNSS and Ubiquity

Chris Rizos, University of New South Wales

GNSS is in a class of its own and the positioning/navigation/timing (PNT) technology of choice for most applications. Why wouldn’t we always use it?

It is affordable, it is a mature technology with many form factors, and its level of performance spans several orders of magnitude — millimeters to meters. There are a bewildering number of permutations of user equipment, augmentation solutions, processing algorithms, and operational procedures to choose from.

However. . . .

VectorNav Supplies IMU for Unmanned Innovation Autopilot Development Platform

Unmanned Innovation, a provider of development platforms for unmanned aircraft systems (UAS), has partnered with VectorNav Technologies to integrate VectorNav’s VN-100 inertial measurement unit (IMU) into Unmanned Innovation’s os-Series Autopilots.

The VN-100 uses the same base IMU components (gyro, accelerometer, magnetometer) that are used to support the VN-200 GPS-aided integrated navigation system surface-mount chip that VectorNav introduced at this year’s Association for Unmanned Vehicle Systems International (AUVSI) North America conference.

Trimble Introduces Next Generation GNSS Survey, Datalink, Mapping Solutions

Trimble R10 rover

Trimble has introduced its next-generation GNSS surveying solution — the Trimble R10, a small, lightweight receiver that introduces new features and technologies, including Trimble HD-GNSS, Trimble SurePoint, Trimble 360, and Trimble xFill, to provide increased productivity.

Announced at the Intergeo 2012 conference in Hannover, Germany, this week, introduction of the Trimble R10 was accompanied by new versions of its field and office software — Trimble Access 2012.20 and Trimble Business Center 2.80 to extend Trimble’s Connected Site survey solution.

Improving GNSS Attitude Determination

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.

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.
