Ultra-Wideband (UWB) technology is gaining recognition for its potential to provide significant benefits in precise positioning and tracking for both terrestrial and space applications. UWB is characterized by its extremely low power spectral densities, immunity to interference from narrow band RF systems, multipath immunity to fading, and the ability to provide precise positioning due to fine time resolution. These unique features make UWB an attractive choice for a wide range of applications.
In a recent development, Control Data Systems (CDS) from Romania has signed a payload services agreement with iSpace to transport CDS’s UWB precision localization technology to the Moon. This technology which combines precision localization with telecommunications was developed specifically for space applications with support from the European Space Agency.
UWB is characterized by several uniquely attractive features, such as low impact on other RF systems due to its extremely low power spectral densities, immunity to interference from narrow band RF systems due to its ultra-wide bandwidth, multipath immunity to fading due to ample multipath diversity, capable of precise positioning due to fine time resolution.
The CDS equipment will be integrated into the APEX 1.0 lunar lander as part of iSpace Mission 3, currently scheduled for 2026. A lunar rover will transport the equipment on the surface to test the localization technology using an antenna that will remain on the APEX 1.0 lander.
As space exploration continues to advance, the integration of UWB technology for precise positioning and navigation holds promise. This mission will mark the first time a UWB payload is transported to the Moon, as well as the first Romanian payload to reach the lunar surface, setting the stage for UWB navigation trials on the Moon.
