¶ General Description
The Echo 63 is a compact active GPS L1 antenna engineered for high-quality reception of satellite signals at 1575.42 MHz. Developed for positioning and navigation applications, it combines a small footprint with straightforward integration into embedded products.
Optimised for the primary GNSS L1 band, the Echo 63 incorporates an integrated low-noise amplifier (LNA) to amplify weak satellite signals at the antenna, helping preserve signal quality before transmission to the GNSS receiver. Delivering RHCP gain of 14 dBiC, together with good impedance matching, it supports stable satellite tracking and accurate position updates.
Weighing less than 4 grams, the Echo 63 is ideal for UAVs and portable equipment where minimising weight helps maximise flight time, payload capacity and overall efficiency. Its omnidirectional radiation pattern and lightweight form factor make it well suited to handheld surveying equipment, compact IoT sensors, drones and portable GPS terminals.
