GPS Module with intregrated GPS patch antenna

GPS module characteristics

This GPS module has high sensitivity, low power and ultra small form factor. This GPS module has SiRF Star III inside and can provide you superior sensitivity and performance even in urban canyon and dense foliage environment. The integrated GPS patch antenna makes the GPS module easy and the best choice to integrate into portable device like mobile phone, PDAs, camera and people trackers. Based on its integrated antenna you save space on PCB and interference with GSM/UMTS antenna.

 

This GPS module offers the advantages as below

• Dimensions (mm): 30 x 11 x 11
• SiRF Star III GSC3f/LP-7989
• 20 parallel channels
• Fast TTFF at low signal level
• Capable of SBAS (WAAS, EGNOS, MSAS)
• Integrated 11 mm x 11 mm GPS patch antenna
• Built-in LNA and SAW filter optimised against GSM bursts
• Wide input voltage 3 - 4.2 V
• Low power consumption
• SMD type with stamp hole

Ultra small size designed for tiny applications

Tracking (people, animals, assets), container tracking, vehicle tracking, PDA, POS terminal, Personal positioning and navigation, automotive navigation, marine navigation
