A major commercial aerospace manufacturer needed to launch small cube satellites into Low Earth Orbit (LEO) and Medium Earth Orbit (MEO), with small to medium sized payloads that supported Commercial Lunar Payload Services. Their goal was to simulate GNSS signals with their rockets, each of which had two antennas.

Military aviation programs provide standard pilot training to ensure that they can handle fighters, drone swarms and other advanced threats. But as they run complex flight training scenarios and face off against live and virtual adversaries, what may be overlooked is the value of using GPS/GNSS simulation to duplicate actual cockpit instruments, rather than relying on facsimile instruments.

An Orolia customer required flawlessly synchronized receivers on two different Low Earth Orbits (LEO) with a time difference that could not exceed extremely tight constraints – within +/-100 picoseconds (ps).

Accident Emergency Call Systems (AECS) are becoming more common in cars to harness the potential of new technologies to help improve road safety. For example, eCall is a European initiative intended to bring rapid assistance to motorists involved in a collision anywhere in the European Union. eCall is mandatory in all new cars approved for sale within the EU after April 2018.

M-Code – it is here. Public Law 111-383, Section 913 requires all military GPS user equipment purchased after FY 2017 to be M-Code capable, unless a waiver is issued the Secretary of Defense.

One reason for the Secretary of Defense to issue this waiver has been the unavailability of M-Code user equipment. With Military GPS User Equipment (MGUE), or M-Code receivers, becoming available to vendors, now is the time to start getting serious about integration and performance testing of MGUE and systems that rely on it.

Today, GPS position capabilities are commonly integrated into vehicles by many major automotive manufacturers and suppliers, along with other signals like radio, TV, Bluetooth, Wifi, and GPS. All these systems need to be thoroughly tested by suppliers and integrated into cars during multiple phases by R&D, Validation and Production.

GPS week zero started January 6, 1980. The 1024 weeks counter ran out and rolled over on August 21, 1999. The week counter then reset to zero, and it has been recounting ever since. The next time the counter will reach week 1023 and rollover to zero is on April 6, 2019.

As GPS receivers are built into more mission-critical devices for difficult application environments, and designed with the emerging capabilities of a multitude of GNSS constellations and augmentation systems, developers and manufacturers need better ways to guarantee performance. That’s where GPS signal generation comes in.

On April 16, 2014, the European Union published a new directive: The Radio Equipment Directive 2014/53/EU. This directive replaced the former Directive on Radio and Telecommunications Terminal Equipment (R&TTE) and has been in effect since June 13, 2016.

 For more than a decade now, we’ve been warned about the vulnerabilities of GNSS and the risks of jamming, as well as the general lack of robustness of GNSS-enabled devices to various interferences. Despite recent examples that the situation is both real and serious, not much has been done since to make the various GNSS/GPS devices that we use daily better able to resist adverse conditions.
