Consistent Satellite Coverage
The Iridium satellite constellation (www.iridium.com)
has constant satellite availability, so there is better coverage at the equator, no need to wait for satellite passes, and greater redundancy than other satellite constellations. This means that there is greater download reliability, and the ability to choose when to upload your data. 24/7 global coverage.
Efficient Data Transfer
Exchanging data with the Iridium system is efficient as handshakes determine what data has been transferred. Therefore look forward to more locations and extra sensor data.
Remotely Upload New Schedules (chargeable option)
Because the Iridium system allows 2-way communications, your tags can be configured to allow a new schedule or other user-chosen parameters (e.g. new virtual fence) to be uploaded after it has been deployed. So if you see that the bird is moving into an area you are interested in, you can increase the GPS locations, and reduce again afterwards, according to the behaviour you are wanting to record.
No External Antenna
Both the GPS receiving antenna and the Iridium transmitting antenna are contained within the housing, eliminating the risk of antenna damage that is always a concern with whip antennas on other technologies.
As with all our PinPoint GPS tags, a user-friendly PinPoint Host allows you to schedule GPS location records when you want, as well as how frequently to upload data or schedule the VHF beacon (if fitted).
Receive temperature, mortality and even proximity data.
Alerts can be sent, or even schedules changed, when your bird enters or leaves a Virtual Fence defined by you. Only available with standard locations processed on board.
Swift locations (or fixes) are more efficient than standard locations, so the tag can record more of them, although they can not be used for virtual fences.
Program different GPS schedules according to whether the bird is within an area specified by you. For example, you may not need so many locations when the bird is near the nest, so you have longer intervals between GPS locations, but when it leaves the area around the nest you can record locations more frequently.
