There are many satellites that are in the Earth’s orbit to give us meteorological information, for example. In fact, from the ground we can see satellites in the sky, as long as they pass close to our area. However, there are also satellites that help us when it comes to orienting ourselves or there are also military companies that use them for their missions.
The Northrop Grumman group of aerospace companies has guaranteed that in 2023 its experimental positioning satellite Navigation Technology Satellite-3 (NTS-3) will take off, after suffering a delay in its launch.
This NTS-3 satellite is being developed to test new positioning, navigation and timing capabilities that could improve the performance of GPS satellites in the future. The Air Force Research Laboratory is developing four Vanguard programs.
GPS and military functions
This experimental satellite will mainly have navigation tasks, with regional coverage and payload defined by software that can be reprogrammed and updated in orbit. This satellite will not affect others that will be launched in the next few years. In fact, it could contribute to improvements for these aircraft.
But this satellite will also have a military function as it will provide GPS location while in orbit to war fighters with an additional PTN signal from orbit. The US Air Force Research Laboratory hopes to be able to test the satellite for at least a year to transfer it to the US Space Force.
The Air Force Research Laboratory signed a contract in 2018 with the company L3Harris Technologies for 84 million dollars so that this company would be the one to manufacture and develop the satellite. After making a design approval, the US government approved its manufacture in August 2020.
The structure of the satellite will be divided into two different parts. In its entirety, it will have communications, power and control subsystems with standard interfaces so that the integration of the payload is simple. It also features a charge adapter ring developed by the Air Force Research Laboratory that allows multiple charges to be applied to the vehicle.
You have to wait until 2023
This is the first time that a product of these characteristics has been delivered as a commercially available product. In addition to the satellite, the Air Force Research Laboratory has received a global satellite navigation system test architecture receiver, a reprogrammable device that works thanks to software that can receive advanced GPS and PNT signals transmitted thanks to the NTS-satellite. 3.
The satellite was originally expected to launch in 2022, but the Air Force Research Laboratory reported in April that it was delaying its launch until the last quarter of 2023. This delay will allow the Laboratory to carry out further tests and experiments to improve the performance of the satellite. system and reduce possible risks that may appear.
