Richard B. Langley explains that there is more to it in developing a practical microprocessor-controlled GNSS antenna array, but it starts with the physics.
Richard Langley submits his 300th and last “Innovation” column in GPS World, where he looks back on 35 years of contribution to the magazine.
The satellite Doppler positioning technique was pioneered in the early space age, using the Doppler frequency shift of satellite signals to determine receiver positions. This concept was first utilized by the U.S. Navy to develop the Transit navigation system.
To further enhance the benefits of combining space-based geodetic techniques, the European Space Agency (ESA) has established the Genesis mission.
GPS applications are vulnerable to signal interference, spoofing and degraded or denied services. Both intentional — jamming — and unintentional signal interference can cause inaccurate PNT and poor navigation performance.
