> The company has designed its signal to be backwards compatible with many existing GPS chipsets, though some are “forwards compatible,” Manning said. But in general, chipsets will only need a firmware update to access the encrypted Pulsar signal. So, they're planning to use the same frequency bands as GPS? And the DoD is okay with this?

Interesting considering only one percent of StarLink’s constellation capacity would be needed for StarLink to provide the service intentionally, and constellation signals can also be used opportunistically. https://people.engineering.osu.edu/sites/default/files/2023-05/Kassas_Navigation_with_multi_constellation_LEO_satellite_signals_of_opportunity_Starlink_OneWeb_Orbcomm_and_Iridium.pdf https://people.engineering.osu.edu/sites/default/files/2023-... https://people.engineering.osu.edu/media/document/2023-08-11/kassas_positioning_with_starlink_leo_satellites_a_blind_doppler_spectral https://people.engineering.osu.edu/media/document/2023-08-11... https://arxiv.org/pdf/2210.11578 https://arxiv.org/pdf/2210.11578 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10056358/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10056358/ Recent somewhat related thread with great comments on GNSS RTK: https://news.ycombinator.com/item?id=40318487 https://news.ycombinator.com/item?id=40318487

It's not like there are no GPS alternatives already: Russia's Global Navigation Satellite System (GLONASS) India's Indian Regional Navigation Satellite System (IRNSS) China's BeiDou Navigation Satellite System (BDS) European Union's Galileo Most consumer GPS receivers can use any or all of these already...
