Signal Sentry 1000, formerly known as GPS Interference, Detection and Geolocation, may now be deployed to collect actionable intelligence for law enforcement, such as tracking high-value targets and protecting critical infrastructure.

Signal Sentry 1000 is a proprietary product that leverages GNSS signal domain knowledge; it is based upon patented technology developed by Exelis through many years of designing and fielding electronic intelligence systems, ITT Exelis said.

“Exelis developed Signal Sentry 1000 to help protect critical infrastructure and to deliver intelligence to law enforcement operations that depend upon GPS availability,” said Kevin Farrell, positioning, navigation and timing general manager for Exelis Geospatial Systems. “Jamming devices can transmit signals capable of disrupting the synchronization of critical infrastructure, such as utility power grids, and timing information of financial transactions. This is why we are continually making improvements in our technology, and the latest milestone achievement is a testament to our goal to deliver actionable interference intelligence to agencies that rely upon GPS operational availability.”

Signal Sentry 1000 technology is a network of threat-detection sensors, which are part of a centralized server executing Exelis‐developed proprietary location algorithms. These sensors can be strategically located around areas of critical infrastructure, such as shipping ports, utilities and government facilities to automatically sense and locate any intentional or unintentional GPS jamming source. Should a threat be detected, users would receive accurate location information and actionable intelligence in order to determine an interference-mitigation plan.

“Signal Sentry 1000 builds upon Exelis expertise in the field of GPS and positioning, navigation and timing. Exelis payloads and payload components have been on board every GPS satellite for nearly 40 years,” said Farrell.  “Today, Exelis is involved in GPS modernization initiatives, building tomorrow’s GPS III satellite constellation by developing and integrating the navigation payloads. Exelis is also providing navigation processing components, precision monitor station receivers, and key components of the system security design for the GPS Operational Control System, also known as OCX.”

“We have been working diligently with AirNet and Cargolux to gain the necessary approvals to bring this one-of-a-kind offering to market. We are very pleased to see this day finally come to fruition,” said Patrick Bertagna, GTX Corp cChairman and CEO. “Over the next few weeks we will work closely with the MNX team to formulate a domestic and international deployment strategy to introduce this offering to MNX customers around the world.”

Designed for customers that ship high value, time or temperature sensitive materials, the technology is well-suited for customers in the life sciences industry. The GPS solution will bring extra security to sensitive shipments, including the transportation of items such as organs, blood, tissue, medications, clinical trial samples and medical devices.

“The GTX Corp tracking platform gives us the ability to better identify and resolve any unforeseen challenges throughout the entire transport and gives our customers added confidence and peace of mind that their shipment is secure at every step,” said Scott Cannon, MNX CEO. “By providing our clients with real-time tracking of their shipments, MNX will offer an unmatched layer of service, security, temperature integrity and reliability.”

The GPS device transmits the latitude and longitude, speed, bearing, altitude and temperature of the plane or vehicle carrying the shipment. The device and GTX platform also provide an easy-to-use customer interface with live shipment tracking and geo-fencing capabilities, allowing customers to know exactly when their mission critical shipments depart and arrive in key destinations. The GTX device is small and light weight (comparable to the size of a standard garage door opener), making it easy to insert in even the smallest packages.

“We realize the capability to track valuable shipments with such detail is especially important to the life sciences industry, especially as this industry continues to expand so rapidly,” said Bertagna.

AirNet, a leading domestic specialty cargo airline specializing in life sciences transportation, and Cargolux, one of the leading scheduled all-cargo airlines, were among the first airlines to conduct a thorough testing process to certify the GTX device, while MNX and GTX continue collaborating to expand the use of the offering to other partner airlines.

Cubic’s asset tracking system is used by the Department of Defense for container tracking, yard management, and shipment monitoring in the Middle East and Southwest Asia.

A system that tracks and monitors valuable high-risk assets for defense and commercial customers has received certification from Iridium Communications, increasing the system’s accuracy and effectiveness. The Iridium constellation of low-Earth satellites provides voice and data services for areas not served by terrestrial communication networks.

The Global Sentinel System, by Cubic Global Tracking Solutions, tracks and monitors assets with two-way, redundant encrypted communications. The system provides up to 2,000 unique geozones for each Global Sentinel device to control precise reporting rules along the supply chain. It can monitor asset conditions including temperature, humidity, light sensing, motion, and container door status.

The latest generation of Cubic’s Global Sentinel System provides continuous global coverage by incorporating the Iridium 9602 short-burst-data transceiver. “As an Iridium partner for the past seven years, we’ve worked closely to integrate the Iridium 9602 transceiver into Cubic’s fifth generation of products,” said Mary Ann Wagner, president of CGTS.

Wagner said Cubic relies on Iridium to provide real-time low latency reporting on customers’ assets in areas where other modes of communication are unavailable. This capability allows for continuous global coverage for reliable secure reporting of asset position, status, and event alerts. “This is essential because of the critical nature of the assets we are tracking and monitoring for our Department of Defense and commercial customers,” Wagner said.

Power-Saving GPS. GPS also plays an important role. With the flexibility derived from geozone attributes for GPS, Cubic can provide an optimum balance between position accuracy and power management.

Cubic’s devices take full advantage of GPS receiver circular error probable (CEP) estimates to set accuracy limits for reporting, explained Randy Shepard, vice president of technology innovations for CGTS. While higher position accuracy may be a challenge for battery-powered units operating for years between servicing, it is often necessary to avoid false alarming for events like route deviation where position accuracy is important.

“One of the unique features of Cubic’s devices is the aggressive manner in which we manage power for all device functions including GPS,” Shepard said. “Using the geozones that are remotely reconfigurable on the device, GPS accuracy and response time can be controlled as a function of geozone.

“As an example, for our current GS-5B receiver used for global tracking and monitoring of shipping containers, the initial default dwell time to capture GPS position is 60 seconds. Our experience is that from a cold start we get a normal lock in less than 45 seconds. The maximum acceptable CEP is 100 meters. If a CEP of less than 100 meters is not received, we do not update position. If a CEP of less than 100 meters is received, we wait up to an additional 60 seconds to improve the CEP. Once a CEP of 10 meters or less is received, the position is captured and the GPS receiver turned off. Again, all four of these parameters are remotely reconfigurable for each of the 2,000 user-defined geozones.”

The other GPS receiver parameter that is configurable as a geozone attribute is whether power is maintained on the receiver to retain satellite ephemeris data. If the position update interval for a geozone is more often than every 15 minutes, data back-up power is usually maintained on the GPS receiver and the satellite ephemeris data is retained. This provides and effective warm start for the GPS and usually results in a much quicker initial position lock, which saves overall power.

To provide real-time asset tracking worldwide, Cubic’s Global Sentinel System relies on a variety of transmission links to communicate the positioning and status of an asset. Based on the location of the asset, the system selects whichever link is the most cost-effective for data transmission. This includes wireless mesh networking, cellular, or the ubiquitous global two-way coverage of the 66-satellite Iridium constellation. The Global Sentinel System relies on the Iridium network’s ability to eliminate blind spots when the asset is out of range of other routing methods.

The GS-5B receiver is installed in a shipping container.
