The Air Force Research Laboratory’s complementary PNT AgilePod prototype aced its first high-dynamic flight tests in November 2021. It also achieved two other firsts: the first test of fully-remote interfacing and alt-PNT data transmission, and the first demonstration of overland/overwater transition performance.

Swift Navigation announced its support of the new STMicroelectronics Teseo V. The Teseo V family is a single-chip GNSS triple-frequency device for automotive use. Swift’s team has been working with ST to ensure the optimization of Swift’s precise positioning solution—comprised of the Starling positioning engine and Skylark precise positioning service—when paired with the STA8135GA Teseo V, the first single-chip triple-band GNSS IC (Integrated Circuit).

Join Adam Barnes, Head of Product at Advanced Navigation, and Ashley Cox, Chief Operating Officer at Cordel, to find out how the latest LiDAR and navigation technologies are revolutionizing surveying.
In this webinar, Adam and Ashley will deep-dive into LiDAR surveying and explain how Cordel leveraged innovative technology to push the boundaries of the industry. They will cover the challenges in UAV-based surveying, in balancing cost and altitude restrictions, with LiDAR point density and INS accuracy to achieve the best overall solution.

Rapidly changing motion means that every aspect of positioning must be carefully re-examined and re-evaluated to avoid costly and dangerous positioning errors. The frequent changes in heading, acceleration and deceleration inherent in rockets, missiles, jet planes, race cars and other platforms — up to 100 times per second! — dictate a very high rate of data inputs from both inertial and GNSS sensors to capture the complex trajectory.

In a race with the U.S. to develop a laser communications network in space, China’s BeiDou GNSS has conducted an inter-satellite and satellite-ground station experiment using using lasers rather than the usual radio signals. The technology could potentially transmit data a million times faster than by radio signal to almost any location. Some experts say it could increase satnav accuracy by a factor of 6 to 40

Future miniaturized sensors, to be used for example in bee-sized drones, mini-satellites, or wearable devices, are likely to include GNSS chipsets supporting accurate outdoor localization and also offering reduced computational costs and power consumption compared to traditional GNSS receivers. The survey various energy-efficient methods for GNSS acquisition and present a discontinuous-reception acquisition algorithm, analyzed with both simulated and measurement-based data.
