OneNav is sharing side-by-side test results comparing its pureL5 GNSS receiver customer evaluation system to a leading Android smartwatch.

OneNav is a Silicon Valley, California-based technology company designed to power high-performance positioning for location-dependent mobile services.

In a challenging urban environment, oneNav averaged six times better accuracy than the smartwatch. Both units used commercial-wearable antennas for testing. While the oneNav system used only GNSS measurements, the smartwatch GNSS results were augmented by inertial sensors.

At the 95th percentile, the pureL5 unit reported 8-meter accuracy compared to nearly 29-meter accuracy for the smartwatch; pureL5 accuracy includes artificial intelligence/machine learning algorithms that improve the system over time.

“The L5 signal is more accurate and reliable than L1, it has higher power and wider bandwidth, and it is less jammable,” said Steve Poizner, co-founder and CEO of oneNav. “We looked at where the market is heading, with the wearables and tracking device markets exploding and the demand for higher accuracy increasing, and we asked, ‘Why keep two bands/two RF chains/two antennas when you can get superior performance with just L5?’”

The oneNav team comprises top GNSS experts from Qualcomm, Apple, Intel, SnapTrack, SiRF, Trimble and eRide who have decades of GNSS and mobile industry experience. The team has expertise in GNSS system architecture, multipath mitigation, signal processing, ASIC design and AI/machine learning, and collectively has filed more than 300 career GNSS patents.

Investors include Google Ventures, Norwest Venture Partners and GSR Ventures.

BizStation,  a database company based in Japan, and u-blox have announced a highly accurate, compact and low-cost high-precision positioning solution for markets in East Asia and Oceania.

Featuring two u-blox modules, the solution delivers centimeter-level positioning accuracy where mobile network service is unavailable, including in maritime offshore surveying, agricultural and industrial vehicle guidance, and UAVs.

BizStation’s precise point positioning (PPP) system covers all territories served by Japan’s Quasi-Zenith Satellite System (QZSS) MADOCA correction service.

The solution leverages the strengths of two u-blox components. The first, a u-blox ZED-F9P multi-band high precision GNSS receiver module, is at the heart of BizStation’s DG-PRO1RWS GNSS receiver.

The second, a u-blox NEO-D9C correction-data receiver module specific to Japan, enables their virtual reference station to receive data on the QZSS L6E-band used by MADOCA.

The PPM (PPP positioning by MADOCA) Android application developed by BizStation then determines the location of the tracked device using the high-precision positioning data transferred via Wi-Fi from BizStation’s DG-PRO1RWS GNSS receiver as well as GNSS correction data from the virtual reference station. The PPM application performs all required calculations using the MADOCA positioning library developed by NEC Solution Innovators Co., Ltd.

The high-precision GNSS solution can be deployed either using a static or a mobile virtual reference station for a wide range of applications such as agriculture, drones, motor sports or surveying systems.

PAR Government, a provider of geospatial and decision support solutions for 57 years, has rebranded its TeamConnect cloud-based situational awareness suite as Sit(x). The commercial Sit(x) solution is designed for enhanced collaboration among government and civilian public safety organizations. PAR Government Systems Corporation (PGSC) is a wholly owned subsidiary of PAR Technology Corporation.

The Sit(x) solution enables individuals and teams to communicate directly by text or symbology and share real-time full-motion video (FMV), geographic information system (GIS) layers, imagery, GPS-derived locations, raster maps, photos and documents.

To complement the Android and Windows support already available in Sit(x), PAR is offering a free iOS app, giving Apple smartphone users access to the technology.

“The Sit(x) name better reflects the ability to provide effective situational awareness for any situation,” said Mark Kozak, PAR Government vice president of Product Innovation. “This results in faster, more informed decision making at the command level and in the field.”

Sit(x) is a TAK server-as-a-service solution based on the Team Awareness Kit (TAK) situational awareness technology that PAR Government developed for the U.S. defense and intelligence community under contract to the Department of Defense. This technology has been deployed under demanding conditions by every branch of the U.S. armed forces over the past decade.

PAR Government created the Sit(x) TAK server-as-a-Service offering specifically to enable real-time communication and information sharing between non-connected public safety personnel during rapidly evolving multi-jurisdictional situations, both planned and unexpected. These include large public gatherings, such as sports events or concerts, and emergency incidents related to terror attacks or natural disasters.

“Sit(x) can save lives, time, and resources by federating unrelated police and fire departments, U.S. government agencies, volunteer search-and-rescue groups, and even private security firms to collaborate as one coordinated entity during a major event,” Kozak said. “Due to its TAK lineage, Sit(x) opens the lines of communications between civilian public safety and the U.S. military, as well as our allies, with no export restrictions.”

The PAR Government Sit(x) offering is a subscription to the Sit(x) TAK Server-as-a-Service software suite in the cloud. Ready in minutes, Sit(x) scales to handle teams of any size and is protected with end-to-end secure connectivity. The suite provides complete lifecycle management – event preparation, rehearsal, training, dynamic response, post-mission playback and analysis, and new response simulation.

The investment by subscribing agencies is minimal because there is no computer hardware to purchase, and the end-user applications are available from the Google Play Store or Apple App Store for free. All server operations and software maintenance are managed 24/7 in the cloud by PAR.

Eos Positioning Systems Inc. announces the release of its Eos Laser Mapping for ArcGIS solution on Android devices. Previously, the free solution was available only on iOS. It allows mobile crews to capture asset locations from a distance with survey-grade accuracy.

“We are excited to provide this already popular iOS solution also to our customers using Android devices,” Eos Chief Technology Officer Jean-Yves Lauture said.

The solution combines technology from geographic information system (GIS) provider Esri, laser rangefinders from Laser Tech, and Eos’ own Arrow Series GNSS receivers.

“The Eos Laser Mapping solution was extremely well-received with its initial release, so we are excited to see the same features now available for ArcGIS Field Maps users on Android devices,” Esri Field Apps Engineering Lead Jeff Shaner said.

The Eos Laser Mapping release on Android supports three workflows, or mapping methodologies: Standard Laser Offset (sometimes called Range-Azimuth), Range-Range (or Range-Intersect), and Range-Backsight (a total station-like method).

The original laser offset solution was released in 2018 by Eos in partnership with Esri and Laser Tech.
