About
The Anywaves GNSS L1/E1 Bands Antenna is the latest-generation single-band navigation antenna from Anywaves, designed for LEO platforms requiring high-accuracy GPS L1 and Galileo E1 positioning. It delivers a realized gain exceeding 6.5 dBi at 1 575.42 MHz (GPS L1 / Galileo E1), with more than 0 dBi maintained at ±60° elevation, providing solid hemispherical coverage in the upper hemisphere. This high gain level maximizes the signal-to-noise ratio at the receiver input and improves positioning accuracy, particularly in low-inclination or maneuvering LEO orbits.
Phase center position variation is held within a sphere of radius less than 1 mm across the full GPS L1 / Galileo E1 band, with elevation-driven variation below 0.4 mm within a ±60° field of view. This stability is crucial for missions where the on-board GNSS receiver is used for precise orbit determination or time-transfer. The antenna is protected by a PEEK radome coated with SG121FD white paint on flight models, providing thermal resistance across a qualification range of −120°C to +120°C and full protection against electrostatic discharges. At 96.6 × 96.6 mm and 103 g, it integrates directly onto any LEO satellite panel in a <1U footprint, with a protruding height of less than 8 mm. Full acceptance testing (RF, mechanical and thermal) is included on flight models. It is ITAR Free.
