MM-520E
MM-520E is a completed solution of GPS by using Ideal module which designed with the single chip core of SiRF Star III to provide GPS the best performance of using the products.
Its high sensitivity can fix the position in any worse environment. MM-520 tracks up to 20 satellites at a time, and shows more than 12 localization massage, this make wireless application close to the life demand. It communicates with other electronic utilities via compatible dual-channel through RS-232 or TTL and saves critical satellite data by built¨Cin backup memory . The built-in recharge battery can conserve Almanac Data. The superior performance of " TTFF " (Time to First Fix ) can fix the position rapidly. It allows the unit operates a fraction of the time and Push-to-Fix permits user to have a quick position fix even though the receiver usually stays off.
