The release of our Solar Argos/GPS PTTs in 2001 was met with great success, but some species of birds preen feathers over a backpack attachment, or live in areas without adequate sunshine to rely on solar power. Therefore, we introduced this battery-powered, GPS-equipped PTT with location data accurate to ±18 m, more precise than the highest Argos location class.
The 105g LC4™ PTT has sufficient battery power to operate for up to 3 years on a standard duty cycle of 1 GPS fix per day and transmission to Argos every 10 days. The 10 locations are compressed into just 2 Argos messages, each containing data from alternating days since the previous transmission. This duty cycle can be customized, but please note that more frequent data collections and/or transmissions will shorten the operational life of the PTT.
Our unique SiV™ technology aligns the timing of transmissions to Argos with times when a satellite is most likely passing overhead. This helps conserve battery power and increases the likelihood of satellite reception of the transmitted messages.
