Product Description
Product Description
EM-5318 GPS module features high sensitivity, low power and ultra small form factor. This GPS
module is powered by SiRF Star IV, it can provide you with superior sensitivity and performance
even in urban canyon and dense foliage environment. With SiRF CGEE (Client Generated
Extended Ephemeris) technology, it predicts satellite positions for up to 3 days and delivers
CGEE-start time of less than 15 seconds under most conditions, without any network assistance.
Besides, Micro Power Mode allows GPS module to stay in a hot-start condition nearly
continuously while consuming very little power. EM-5318 is suitable for the following applications:
Automotive navigation
Personal positioning
Fleet management
Mobile phone navigation
Marine navigation
Notebook navigation
