As low Earth orbit Positioning Navigation and Timing (LEO-PNT) initiatives gain momentum worldwide, Europe is moving forward with ESA’s Celeste In-Orbit Demonstrator (IOD). Thales Alenia Space, prime contractor of one of the two consortia developing the IOD, has entrusted Anywaves with the design and delivery of the antennas required for the mission, including the navigation payload antenna.
Compact and Robust Design for a High Performance RF Link
Developed, qualified and delivered in less than 18 months, this navigation payload antenna, intended to radiate a navigation signal from the low Earth orbit, features an innovative design.
Optimized for small satellite platforms, it combines compactness and performance through a quadrifilar helix configuration and a deployable mast technology. The antenna offers an excellent ratio between stowed and deployed dimensions, ensuring homogeneous signal distribution on the ground with consistent power and quality, even in challenging environments. Its circular polarization and helical structure enable reliable and accurate transmission, while the deployment mechanisms are specifically designed to withstand launch loads and meet the requirements of low Earth orbit.
