Garmin Astro 220

The Garmin Astro is a unique product which gives you the ability to track your dog by GPS while hunting. The Astro resembles many of the other Garmin handheld devices but with the addition of a second antenna. In fact, it is really just a modification of the 60CSx. There is a secondary transmitter known as the DC-20 which is attached to your dog. Your dog’s position is then relayed to the Astro so you can see your dog’s position on the Garmin Astro screen.

Position reports come every five seconds and you can view a trace of where your dog has been on the Astro. The “Dog Tracker” will also give a compass heading and speed indication for your dog. Alarms can also be set to indicate when your dog is on point.

The DC20 transmitter can be attached via a neoprene harness strapped to the collar, or threaded to an existing one inch collar. The Garmin Astro battery should last about 20 hours and the collar will hold a charge for about 17 hours.

Have lots of dogs? Not to worry, the Astro can track up to five different DC 20 devices and thus five dogs. The range is about five miles in a best case scenario. The Garmin Astro also has the ability to set waypoints for where you found your prey and timestamps with a date, time, altitude, and location

How GPS Work

GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers take this information and use triangulation to calculate the user's exact location. Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map.

GPS

The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use GPS.
