UWB radio and antenna technology may also enable precise positioning and ranging with centimetre-accurate localisation, surpassing some traditional approaches to GNSS systems. Meanwhile, the adoption of new-generation satnav constellations, such as the US’s GPS L5 and the EU’s Galileo E6, as well as regional systems such as NavIC in India, will soon provide uncrewed vehicles with improvements in position accuracy and signal strength, as well as enhanced signal reception reliability, with less susceptibility to spoofing, multipathing and congestion-driven interference. Applications such as photogrammetry, agriculture, and search and rescue depend on highly precise positioning, so antennas with the right filtering arrangements for such frequencies will be especially prized in vehicles destined for these markets. NavIC is notably challenging in this regard due to transmitting in the S-band – an unusual quality for GNSS constellations, which are typically L band systems (and newer satellites all work in the lower L band) – so antennas tuned for receiving NavIC signals are best sought in India. Despite all of this, artificial intelligence (AI) may yet prove to be the biggest
