MALÅ GX

MALÅ GX is an integrated GPR solution with a wide range of antenna options and measuring devices. Through unique, hyperstacking, HDR technology, MALÅ GX offers significantly faster data acquisition rates, with outstanding signal-to-noise ratio and depth penetration. An easy-to-use GPR solution on a rugged platform with excellent detection capabilities for a wide range of applications.

MALÅ GX is an integrated GPR solution with four MALÅ GX antenna options: GX80, GX160, GX450 and GX750. Built around a fast 1.6 GHz Intel Atom processor and using a high-resolution display to present the 32-bit data, the MALÅ GX Controller delivers excellent performance and outdoor visibility. The MALÅ HDR technology utilizes hyperstacking to reduce random noise; providing deep penetration with an unparalleled level of data quality. The easy-to-use controller has a built-in battery to simplify handling in the field.

MALÅ GX antennas feature an integrated DGPS for accurate positioning and the solution supports the use of external GPS. MALÅ GX solutions support a wide range of distance measuring devices. The new WiFi option enables wireless data collection, making it even easier to use in confined spaces as well as irregular landscapes. Normal working range varies between 25-100 meters depending on the surroundings.

System configuration

Every MALÅ GX solution contains two separate components: the GX Controller and the GX antenna. These are connected either through a single cable or WiFi. MALÅ GroundExplorer is typically configured as either a push- or pull-system.

To configure a push-system, the MALÅ GX Controller and a MALÅ GX antenna are mounted on a Rough Terrain Cart.

To configure a pull-system, an encoder wheel is fitted to the mounting block on the back of the antenna. The GX Controller is then carried with the monitor holder and the antenna assembly can be pulled with a pulling handle or a strap.

The MALÅ GX antenna options are;  GX80, GX160, GX450, and GX750, all based on the latest HDR technology.

Case Stories

GPR method in the unseiling of Tomb of Christ

GPR plays an important role in the unsealing of the Legendary Tomb of Christ

Thousands of people are visiting the Church of the Holy Sepulchre in Jerusalem every year. This is the place where Christ shall have been buried and resurrected from the dead.
This historical venue needed to be thoroughly investigated to reveal what is hidden under the floor and behind the walls.
