L30, a GPS receiver module, which is based on the lastest SIRFstarIV ROM version 2.2, features extremely compact profile of 9.0 x 9.0 x 1.6mm and low current consumption of only 31 mA during tracking. Highest sensitivity down to -163dBm for tracking satellites along with lowest Time-To-First-Fix fulfill the toughest requirements.

L30 supports aided-GPS function without the necessity of downloading data from server since it automatically captures ephemeris data from satellites locally and predicts ephemeris over 3 days without server assistance.

With embedded active jammer remover, L30 can track and remove up to 8 CW (Carrier Wave) type signals up to 80dB-HZ signal level. This feature ensures fast and accurate navigation in hostile signal or high noise environment.

Its high sensitivity, lower power consumption and 48-PRN channels make L30 the best choice for portable device such as vehicle tracking, personal tracking, asset tracking, connected PND and security device.

Packaging

The module is sensitivity to moisture absorption. Before reflow, Module should be baked for 192 hours at temperature 40℃+5℃/-0℃ and <5% RH in low-temperature containers, or 24 hours at temperature 125℃±5℃ in high-temperature containers. Care should be taken that plastic tray is not heat resistant. Module should be taken out before preheating, otherwise, the tray maybe damaged by high-temperature heating.
