Scientific research

The Gradiometry is a principle method used inside measuring system. With an array of data received from hight-precision accelerometers, we build a Gravity map containing a three-dimensional field characterization.

img

This map contains information on gravitational anomalies originating from the interaction of individual physical objects e.g. metals, fluids, gas, etc.

img

Depending on the resolution of the map, it is possible to define the density and physical coordinates of the objects that generate such anomalies and may range from large space bodies to relatively small objects. Density composition of such objects differ from the rest of the environment in the survey area.

«GST» components

img

Measurement unit. A temperature-controlled system containing a group of high-precision MEMS accelerometers, ADC and temperature sensors.

img

Computing unit. Designed for data noise processing and interaction of peripheral sensors. Provides operation of external interface, memory modules and power system.

SimuTool_logo

«GST-Simutool» is a software environment for modeling and simulation of gravimetric processes designed for creating three-dimensional gravitational maps, conducting virtual experiments and performing high-level processing of the data recieved from the «GST»-based devices.

«GST» Navigator

The first project to use the «GST» technology is the Gravimetric navigation system — a hardware and software platform that is completely independent from satellites and antennas. It is designed for making, checking and correcting routes for various types of vehicles (air, water, underwater) and foot expeditions (including underground ones).

airplane-icon
ship-icon
submarin-icon

Navigation/route correction
For air, water, underwater vehicles

minerhat-icon
snow
nogps2-icon

Navigation in extreme conditions
Routing underground and in arctic

Features

Does not require radio or GPS signals. Gravity waves can not be jammed or distorted.

«GST» navigator can be used anywhere in the world, at any depth or altitude.

The system may be stationary (installed on large vehicles) or mobile (to use during foot expeditions).

Navigation example

Step 1. Survey, map creation

img

An aircraft equipped with a gravity navigator flies along the route

img

Survey results are processed, tensor calculation is performed

img

Based on the tensor components and topographic data collected a gravity map of the area is created

Step 2. Data collection in the field

img

The foot group conducts a series of measurements using the mobile version of the gravity navigator

img

Calculation of tensor for measured points is performed

img

A tensor map of the area is created

Step 3. Determining the location

img

Searching position of the local tensor map within the boundaries of the global map

img

Search results allow to determine the boundaries of the area on the global map as well as to locate the topographical coordinates for the most recent route point of foot expedition
