The China Satellite Navigation Office (CSNO) announced completion of two years of testing of BeiDou inter-satellite links, an innovative feature of the GNSS that will reportedly produce greater accuracy for users on Earth. The test campaign encompassed 29 satellites of the third generation (BDS-3) of the now global system.
Tersus GNSS has released the BX40C RTK Board to support its series of GNSS boards and provide high-accuracy, fast positioning services. Powered by new Tersus ExtremeRTK GNSS technology, the BX40C Board can support multi-constellation and multi-frequency all-in-view satellite tracking.
A new marine-certified quad-band GNSS receiver, the LD900 from VERIPOS, delivers accurate and reliable positioning in demanding offshore environments. The LD900 can track four GNSS frequencies simultaneously to ensure a precise position is always available at sea.
The MEMS-based inertial measurement unit (IMU) represents the single biggest positioning and navigation advance of the last 20 years. That assertion is made during the first of three panels in the webinar “Inertial Technology for Robotics, UAVs and other Applications,” freely available on May 6. The 1.5 hour presentation examines how this breakthrough plays in the fields of autonomy, high dynamics and challenging environments, including on the frontiers of space.
Three experts takes a close-up look at contemporary and emerging inertial sensor technologies and applications, from the laboratory to the factory to the field. Register here to attend. The webinar is sponsored by Sensonor.
MEMS (micro-electromechanical sensors) make possible a miniaturization of size, weight, power requirements and cost never thought achievable before. When MEMS inertial navigation pairs with GPS for navigation, the key factor is the error budget of each sensor and how that plays into the accuracy of the solution. Attendees will learn how the new inertial sensors’ reduced error budgets translate into higher system performance.
The presentation begins with the current state of the inertial art, delivered by a recognized expert. The second speaker describes a high-accuracy tactical-grade inertial measurement unit (IMU) with increased accelerometer performance to support demanding guidance and navigation applications.
This knowledge is taken to the field to examine the IMU’s role in successful satellite launch missions during the third panel. The attitude determination and control system (ADCS) rises to the challenge of an extremely demanding environments and set of requirements. A satellite moving at a speed of 7,500 meters/second over ground requires precise maneuvering, stabilization and point in order to obtain imagery at 1-meter resolution.
Questions from the audience are actively encouraged and will be addressed by the three speakers in the final portion of the webinar.

A new API for GNSS simulators enables greater accuracy, integrity and control for growing sensor-fusion testing needs. Spirent Communications’ SimHIL, an integrated hardware-in-the-loop (HIL) testing software API for Spirent GNSS simulators, brings high-fidelity GNSS signal simulation with low latency to automotive industry HIL testbeds.
EMCORE Corporation, a provider of advanced mixed-signal products serving the aerospace, defense and broadband communications markets, received the 2019 Raytheon Integrated Defense Systems (IDS) 5-Star Supplier Excellence Award for performance and partnership.
That aside, some controversy has arisen in the world of competitive running, and self-competitive running as in Personal Bests, or PBs. Runners find their fitness trackers and watches don’t necessarily tell them the truth in terms of distance travelled. In fact, they very rarely tell the absolute truth. Which matters.
Swift Navigation and Deutsche Telekom announced a partnership to incorporate Swift’s Skylark Cloud Corrections Services within Telekom’s communications infrastructure through its new Precise Positioning product offering.
