The SPIDAR® family of devices enable networking of multiple GPR systems for a wide variety of applications. SPIDAR® allows networking of any number of Noggin® and pulseEKKO® PRO GPR units to create virtually any multi-channel and WiFi-enabled GPR deployment imaginable.


SPIDAR® uses a tree architecture as depicted, with a computer at the top of the structure controlling one or more GPR systems via wired or wireless Ethernet. SPIVIEW® control software operating under Windows on the computer provides an integrated user-friendly control and real-time display of all systems status and GPR data

Noggin® and pulseEKKO® PRO GPR systems are network-enabled using SPIDAR® Network Interface Controllers (NICs). NICs are microprocessor-based modules that provide complete control of Noggin® or pulseEKKO® PRO GPRs and communicate with the world via wired or wireless Ethernet.

When a multiplicity of NICs must operate together simultaneously, a SPIDAR® HUB provides coordinated communications, power management and positioning synchronization for the NICs and their associated GPR unit. Each HUB supports up to four NICs; additional HUBs can be connected enabling an unlimited number of NICs and GPR systems. Practical power management for advanced portable configurations underpins the design of the HUBs, NICs and GPR systems.

Interconnection of peripherals such as odometers, power supplies, beeper/triggers, GPS and laser tracking units, or additional geophysical sensors, is designed into the SPIDAR® architecture.

SPIDAR® is a configurable product.


SPIVIEW® for SPIDAR® is PC-based software that provides the command and control of the GPR network. SPIVIEW® defines a “platform” as a network of GPR units that move in a coordinated fashion with common positioning control. The platform definition includes the relative position of every GPR system in the network as well as peripheral devices used during data acquisition such as the odometer and GPS. SPIVIEW® provides the ability to set up, save and re-call platform configurations. During data acquisition, SPIVIEW® displays one window for each GPR system. The user can also open any window in Full Screen mode to take a closer look at the data collected by that particular GPR. Individual GPR data files are stored in standard Sensors & Software DT1 files.

SPIVIEW® makes collecting grid data easy. The software indicates collected and uncollected lines. The user can add new lines, reverse line directions and easily position lines around obstructions in the survey area.

SPIVIEW® provides powerful real-time data analysis and imaging capabilities. Grid files can be previewed with EKKO_Mapper anytime during grid data collection. The operator can open the current grid in EKKO_Mapper and move up and down through the depth slice images.
