The defense industry has always depended on navigational technology to address security risks of various magnitudes, from border protections to monitoring international territorial agreements. Likewise, global commercial industries such as aviation, maritime, geosciences and logistics, among many others, depend on navigational advancements to develop and deliver products and services that meet their customers’ requirements.
Today’s modern navigational system utilizes two advanced systems: inertial and satellite to create what is currently the most powerful simulation and detection tool available – the EGI GPS (Embedded GPS Inertial).
No Stopping Navigation Technology
Understanding EGI entails a knowledge of GNSS (global navigation satellite system) which has advanced navigational technology. GNSS consists of all existing equipment that receives and processes signals from multiple satellite systems, notably the GPS (Global Positioning System).
Like the INS, relying only on GPS is not enough to meet the challenges of navigational demands. On its own, GPS is constantly augmented with other technologies to make it as powerful and useful as it can be. On the possibility that GPS is down, experts have developed the EGI GPS (Embedded GPS Inertia), combining inertial sensors of with satellite signals and enabling navigation in GPS-denied environments.
Busting the Bugs: Location Inaccuracies
EGI GPS complements the capabilities of the pioneering INS (Inertial Navigation System) which utilizes a computer, accelerometer (senses motion) and gyroscope (senses rotation) to pinpoint an object’s position, direction and speed of movement. INS can succumb to integration drifts which are slight errors in acceleration and velocity measurements (due to changes in an object’s position and speed and in the lessened sensibility of sensors and receivers). These drifts can be addressed and corrected when you combine the inertial system with satellites.
The EGI structure combines an inertial unit (gyroscope-based ring laser) with a powerful multi-channel GPS receiver. With this, the EGI delivers three navigation solutions: inertial navigation only, GPS only and a mix of GPS/INS solution. As it is, the EGI offers a lightweight yet more accurate navigation and guidance unit for all industries that rely on precise location, movement tracking and object orientation to deliver a variety of services and products that translate to convenience and enjoyment for everyone.
Today, EGI is used in guided missiles, spacecraft, aircraft and submarines to deliver more accurate positional data for various purposes. Leading players in EGI GPS and GNSS manufacturing as a whole includes major aerospace and defense technology firms.
