SIMCom brings to you this innovative GPS module that is high on performance, durability, and reliability. This standalone GPS module is made using Surface Mount Technology, and is a key component for various mobile designs.
The SIM28ML is manufactured with precision and enriched with MediaTek navigation system to ensure a high level of accuracy, sensitivity, and Time to First Fix (TTFF). The module can deliver high-performance while consuming very less power (it consumes only 17 mA for acquisition and 16 mA for tracking). It can also track 165 dBi signal without network assistance.
The SIM28ML is also highly compatible with most navigation applications like autonomous GPS, Satellite Based Augmentation Systems, Differential GPS, and Assisted GPS.
