The Geostationary Earth Satellite (GEO) 7 payload will also form the FAA's Wide Area Augmentation System (WAAS), which corrects and improves the information provided by Global Positioning System (GPS) satellites to give commercial and civilian pilots a precise approach and departure guidance.
The Spire and GeoOptics payloads will measure GPS satellite navigation signals passed through Earth's atmosphere to derive information about weather and climate. Rocket Lab's fourth launch will be dedicated to launching CubeSats sponsored by NASA and developed by U.S. research institutions.

However, satellite-based solutions based on only one single constellation, such as GPS-the US constellation, are not sufficiently reliable. These GNSS solutions lack of satellite visibility in certain areas of the city where most of these services are offered and are vulnerable to positioning errors, such ...
