GPS World Webinar 2021

Thank you for Joining Calian at the GPS World Webinar 2021

At the 2021 GPS World Webinar, Calian led an in-depth discussion about the Positioning, Navigation, and Timing (PNT) challenges and benefits of multi-constellation and multi-signal GNSS.

In recent years, the number of GNSS constellations has grown from when GPS was the only constellation and most applications were single-frequency. Today, there are four GNSS constellations, with each constellation supporting three or more signals. While the GNSS systems grew, the radio frequency environment also expanded and became more congested with LTE and the anticipated Ligado (North America) signals. Both signal types are close to the GNSS band, and LTE signals have harmonics that fall within the GNSS band. This webinar will enumerate the benefits of multi-constellation and multi-signal PNT using the GNSS timing application space as a case study. It will conclude with a discussion of the challenges of operating in a congested radio frequency space.
