16 Nov What is a MEMS GNSS/INS?
A MEMS GNSS/INS is a sophisticated technology combining two distinct but complementary systems to provide highly accurate location and movement data. MEMS, or Micro-Electro-Mechanical Systems, refers to the miniaturization of mechanical and electro-mechanical elements. These tiny sensors, often used in Inertial Navigation Systems (INS), can detect changes in motion and orientation.
On the other hand, GNSS (Global Navigation Satellite System) is a technology that uses satellites to provide geospatial positioning. It encompasses systems like GPS (USA), Galileo (Europe), GLONASS (Russia), and BeiDou (China).
When these two systems are integrated, the result is a MEMS GNSS/INS solution. This combines the broad, global positioning data from GNSS with the precise, immediate movement data from MEMS-based INS. Such a system is especially valuable in environments where GNSS signals might be weak or interrupted, as the INS can continue to provide accurate data through its sensors.
The MEMS components in this setup, due to their small size and low power consumption, make the entire system more compact and energy-efficient. This is ideal for applications like drone navigation, autonomous vehicles, and mobile mapping systems, where size, weight, and power efficiency are critical. The integration leads to enhanced accuracy, reliability, and performance in navigation and positioning tasks.
