An Exemplary Real-Time GNSS Network

For more than 20 years, SWEPOS has consistently demonstrated the full potential of real-time GNSS networks Standing in the main control center of Sweden’s real time GNSS network (RTN) system, I feel like I could be standing in NASA Mission Control. A marvel of infrastructure created by Lantmäteriet, the country’s mapping agency, the center has...

Capturing Today’s (and Tomorrow’s) Constellations

Access to all GNSS constellations provides better data, better results Enhancements made to improve the handling of satellite systems (also called constellations) and the increasing number of signals produced by these systems provide a tangible benefit to any solution that requires precise positioning.  Depending on the time of day and the geographical location, some of...

Looking Forward: Air, Space, and Ground

Ingenuity Breaks New Ground for UAVs – on Mars

NASA’s Ingenuity Mars Helicopter continues to set records, flying faster and farther on Sunday, April 25, 2021 than in any tests it went through on Earth. The helicopter took off at 4:31 a.m. EDT (1:31 a.m. PDT), or 12:33 p.m. local Mars time, rising 16 feet (5 meters) – the same altitude as its second flight....

Remote Sensing with Satellites

The commercial satellite remote-sensing industry has rapidly evolved over the past two decades, from both the technology and market perspectives, so that satellite imagery has become an integral part of many industries. For example, national, high-resolution maps greatly benefit the civil government and mapping portal industry, especially with cities refreshed on an annual or more-frequent...
