Detail Information

Description : 1. Featuring excellent anti-signal interference capabilities and amazingly low current consumption, D-18 is the most compact GPS antenna module currently available on the market. Thanks to our cutting-edge technology that makes the device the tiniest possible without sacrificing performance. D-18’scomprehensive coverage can extend to far-off horizon, performing excellently in foliage or urban canyon environment – even in the presence of electromagnetic interference!
2. Coming up with diminutive but substantial enclosure plus unparalleled performance, D-18 is compatible with almost every GPS receiver model available on the market and provides a perfect alternative for a vast range of GPS applications in the fields of AVL, vehicle navigation, aviation and military.
3. Features:
(1) Excellent anti-signal interference capabilities and amazingly low current consumption.
(2) Microscopic & rigid structure suits well military and other applications demanding high degree of confidentiality.
(3) Ultra-high sensitivity.
(4) Module board available for embedded applications.
(5) Ideal for PDA, HPC and other computing devices running GPS applications.
(6) High temperature stability.
