A new dimension in real-world PNT testing has arrived. One of the most critical things to predict for chips, receivers and devices using alternative or back-up PNT technologies is how they will actually perform without GPS. Filling this need, the U.S. Air Force 746th Test Squadron has declared Initial Operational Capability (IOC) for its new truth reference, the Ultra High-Accuracy... read more

Air Force jam-proof reference system ready to support testing

Locatalite transceiver installation in the White Sands Missile Range Ultra High-Accuracy Reference System, provided by the U.S. Air Force for testing equipment under conditions of GPS jamming.

The U.S. Air Force 746th Test Squadron has declared Initial Operational Capability (IOC) for its new truth reference, the Ultra High-Accuracy Reference System (UHARS), which employs LocataLite transceivers. Even when GPS is being completely jammed, UHARS provides extremely accurate positioning, navigation and time (PNT) over the large area of White Sands Missile Range (WSMR) in New Mexico that the system was designed to cover.... read more

In defense of PNT: Multi-GNSS to the rescue

For more than 41 years, many of us who were there in the beginning have been discussing the attributes, capabilities, enabling features and shortcomings of GPS and other space-based PNT (position, navigation and timing) systems. You have likely heard most of them; historically they go something like this: The signal is weak. The signal is easily jammed. The signal can be... read more

Wide-Area Wireless Network Synchronization with LocataNets The United States Naval Observatory conducted several independent frequency synchronization experiments in Washington, D.C., using an alternative PNT technology in multiple network configurations. The results suggest that sub-nanosecond time transfer using this technology may be possible over wide urban areas, and that it could thus serve as a GPS augmentation or back-up solution over... read more

OxTS Creates Locata + INS System

August 7, 2015By
The Inertial+ by OxTS improves measurements from a GPS receiver.

OxTS has successfully integrated a Locata receiver with its Inertial+ to create the first Locata+INS device, according to both companies. The device is capable of achieving centimeter-level accuracy where GPS systems fail. The Inertial+ series, first developed in 2008, was designed for users who had an external GNSS receiver already, but still wanted to gain the benefits of an inertial system. The... read more

NASA-UAS-O

NASA plans to install a Locata network (LocataNet) as the core positioning technology for safety-critical unmanned aerial systems (UAS) research at its Langley Research Center in Hampton, Va., according to an announcement by Locata. NASA Langley is tasked with performing rigorous and repeatable scientific evaluation of new 
UAS safety and technology concepts under development. The LocataNet will provide high-precision non-GPS-based... read more

Locata Warns: Lessons to Be Learned from GLONASS Spasm

April 15, 2014By
Locata-O

Calling it an “unprecedented and deeply worrying total disruption . . . [that] shook the industry,” Locata Corporation reiterated its call for redundant terrestrial systems to back up GNSS in the wake of the April 1 11-hour GLONASS system outage. Nunzio Gambale, Locata CEO, said “We have been telling the industry for years that you cannot have a critically important... read more
