I got a Garmin Astro that im playing around with and have a question someone might be able to answer.

In wich format does the unit get the coordinates from the collar? Is it with longitud and latitud like this "22.567026,114.051266" or in some other way?
Im just thinking about how the unit tells the map where to show the position.

hmm damn hard to explain in a language i dont master

The Astro GPS Dog Tracking System is composed of two distinct parts: the dog's transmitter and a small handheld receiver . The dog transmitter is easily attached to your dog's collar, while the receiver features a color screen that allows you to track your dog on the screen. The device tells you exactly how far away the dog is and whether it is running, sitting, on point, or tree quarry.The color screen on the Astro is constantly plotting each dog's track. The units the dogs are wearing transmit their new coordinates (longitude and latitude)to the handheld unit every five secondsThe Astro also has a map page to illustrate where a dog is and where it has been – in relation to the hunter – and allows hunters to determine if they have covered nearby ground. For even more detail, hunters can download their waypoints and tracks – as well as their dogs’ tracks – to MapSource or Motionbased.com™ for analysis on topo maps or Google Earth after the hunt.
In flat, unobstructed terrain, the Astro transmitter and receiver have an effective range of up to five miles. Battery life is 17 hours on the rechargeable collar and greater than 20 hours on the receiver, which is powered by two AA batteries."
It can track up to 10 dogs
The Astro has a card slot that allows users to insert optional pre-programmed topo maps or road maps, which can be invaluable in an unfamiliar area. Topo maps give hunters an idea of the most productive areas to hunt, while road maps feature the same basic functions as an automotive GPS navigation unit – even in rural areas. The optional road map data can also give directions to motels, gas stations, restaurants, and even veterinarians.
The Astro also calculates area, which is ideal for determining the acreage of a piece of property or the exact size of a food plot. The unit has location-specific sunrise/sunset and moonrise/moonset tables (ideal for determining legal hunting hours) and a hunting and fishing calendar that suggests the best times to be out in the field.
the Astro is also a full-featured handheld GPS based on the GPSMAP 60CSx so when the hunting season is over, the Astro can pull double-duty for hiking, boating, or car trips.
