Atlantik Elektronik presents the Multi-Constellation GNSS Module from Quectel

Extremely compact module LG77L with ultra-low power consumption

Planegg, Oktober 6, 2020

Atlantik Elektronik, provider of innovative wireless solutions, presents the multi-constallation GNSS module LG77L from Quectel, the worldwide leading supplier of 5G IoT, GNSS, Wi-Fi and cellular modules.

The LG77L is a multi-constellation GNSS module that supports concurrent reception of GPS, GLONASS, BeiDou and QZSS. With 33 tracking channels, 99 acquisition channels and 210 PRN channels, it can acquire and track any mix of GPS, GLONASS (or BeiDou) and SBAS signals.

Compared with single GPS system, enabling multiple GNSS systems generally increases the number of visible satellites, reduces the time to first fix and increases positioning accuracy, especially when driving in rough urban environments.

Combining advanced AGNSS feature such as EASY™ (Embedded Assist System) and low-power modes such as GLP (GNSS Low Power), LG77L achieves high performance, low power consumption and fully meets the industrial standards. EASY™ technology allows the module to calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal RAM, so LG77L can fix position quickly even at lower signal levels with low power consumption. With GLP technology, LG77L can adaptively adjust the on/off time to achieve a balance between positioning accuracy and power consumption according to the environmental and motional conditions.

Its super performance makes LG77L ideal for industrial PDA, consumer and industry applications. Extremely low power consumption makes it a great solution for power-sensitive applications, especially portable devices.

Key Benefits:

  • Extremely compact size: 7.0 mm × 7.0 mm × 2.0 mm
  • Multi-GNSS engine for GPS, GLONASS, BeiDou (optional) and QZSS  
  • Support antenna detection and antenna short-circuit protection functions
  • Support anti-jamming and multi-tone active interference canceller
  • Multiple low-power modes ensure ultra-low power consumption
  • Support UART and I2C Interfaces
  • Maximum fixed update rate up to 10 Hz
  • Support SDK commands developed by Quectel
  • Support AGNSS

“With positioning technologies moving on, requirements for higher precision, lower cost and lower consumption grow rapidly. With the latest generation positioning module at sub-meter level, we present a top class high precision positioning module from Quectel", explains Ottmar Flach, Managing Director Atlantik Elektronik GmbH.

The LG77L is now available for order at Atlantik Elektronik.
