GPS receiver module with intregrated GPS patch antenna

GPS receiver module characteristics

This GPS receiver module has been designed to address applications where placement flexibility is very important along with stand alone operation, high level of integration and low power consumption. This series are the smallest, autonomous, fully featured GPS receivers, optimised for standalone operation. The GPS modules are complete SiP (System-in-Package) featuring advanced miniature packaging technology and an ultra small footprint designed to commit unique integration features for high volume, low cost and low power applications.   This GPS receiver module has SiRF Star III inside and can provide you superior sensitivity and performance even in urban canyon and dense foliage environment. The GPS antenna patch can be placed somewhere in the enclosure. Last but not least the patch antenna can be replaced to coaxial cable Hirose W.FL to SMA/M bulkhead. GPS module 17x17 is pin compatible to GPS module 18x18.

This GPS receiver module offers the advantages as below

• Dimensions (mm): 17 x 17 x 2.2 (GPS module without GPS patch antenna)
• Coaxial connector W.FL
• SiRF Star III GSC3LT(f)
• 20 parallel channels
• UART and SPI communication
• Fast TTFF at low signal level
• Capable of SBAS (WAAS, EGNOS, MSAS)
• Integrated 18.4 mm x 18.4 mm GPS patch antenna
• Built-in LNA and SAW filter optimised against GSM bursts
• Wide input voltage 3,25 - 5.5 V
• Low power consumption: Tracking 75 mW only including active GPS antenna
• 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
