The Rainier-S20 is a solar-powered, GPS-equipped Argos transmitter (PTT) tag specifically designed for birds. The Rainier-S20 is suitable for birds weighing as little as 650 grams to be tracked with GPS precision and accuracy over land and sea for multiple seasons.
The Rainier-S20 has a very low profile and sports a powerful and flexible antenna, smooth surfaces, and rounded edges with no sharp/cutting finishes. The design helps minimize mass, drag, and risk of injury to the bird.
The tag’s intelligent, low-power design incorporates our latest Argos-certified transmitter, a 48-channel GPS receiver, temperature, battery voltage, tilt, and accelerometer sensors. A non-volatile memory with the capacity to store up to 58,000 locations (about 6.5 years of GPS locations based on one location per hour). The small, solid cast 20 g package is waterproof and tested to 100 m depth.
