Vital Alert develops autonomous vehicle navigation for underground parking

Vital Alert, through its wholly-owned subsidiary, Waldo Technologies, has developed a positioning and navigation system for autonomous vehicle underground parking.

The system uses VLF (very low frequency) signal beacons and a miniaturized vehicle receiver to navigate a driverless vehicle within radio-frequency-denied environments such as tunnels and multi-story underground parking garages. The system provides position accuracy of less than 7 inches, and is not affected by objects such as other vehicles.

Rebuilding Their Future Foundation

Vital Alert provides Intrinsically Safe through-the-earth communication system for coal mine refuge chambers.

This system was installed and tested in the Blacksville West Virginia coal mine in June 2019.

It provides high-quality voice communication between an underground refuge chamber and surface personnel.

NIOSH Underground Noise measurement study

Vital Alert completes its four-year study for the National Institute of Occupational Safety and Health (NIOSH) to measure and report underground background noise.

This Vital Alert study will be used by various U.S. agencies to better understand underground background noise at various frequencies in the radio spectrum.

Federal Resources Open House

December 12, 2018

Vital Alert demonstrated and exhibited its through-the-earth radio terminals at the Federal Resources Open House held in Warren, Michigan on December 12, 2018.

Federal Resources is a provider of equipment to the U.S. military and government first responders.

This Open House was selected exhibition of technologies relating to subterranean intelligence, surveillance and reconnaissance, and was attended by participants of the Community of Practice for Subterranean and dense urban environment (DUE) materiel solutions.

Toyota ITS Phase 3 Intelligent Transportation System

On November 26, 2018, Vital Alert demonstrated its vehicle and pedestrian positioning system for dense urban environments in Shinjuku, Tokyo, Japan for Toyota ITS (Intelligent Transportation System).

The system uses very low frequency signals to accurately determine the location position of objects in urban traffic intersections including vehicles, bicycles and pedestrians.

The system is intended for dense urban environments where GPS signals are unavailable or inaccurate.

The demonstration validated the <0.4 meter accuracy objective. GPS position accuracy showed a mean error of >30 meters at the same intersection.

The Tokyo demonstration intersection is typical of many in Tokyo and in other large cities.

Thunderstorm 18-2

August 13-17, 2018

Vital Alert validated at U.S. Army Thunderstorm exercise in metropolitan New York City and Fort Hamilton.

Vital Alert participated in Thunderstorm 18-2 on August 13-17 to validate our capabilities in subterranean communication.

Our CommPac 3 kg radio used for this exercise was transported below ground and deployed to provide a through-the-earth communication range of 100 meters.

This validation demonstrated high voice quality, direct through-the-earth communications from a subterranean Mobile Ad-Hoc Network (MANET). The subterranean network was provided by Persistent Systems MPU5 radios.

This demonstration was carried out approximately 250 feet below central Manhattan where new subway lines are being constructed

Through-the-earth voice interconnectivity with Persistent Systems was also demonstrated in the NY World Trade Center Tower 3 in the subterranean levels and on floors 70-80. Very low frequency direct voice communication from the top to the bottom of a tall building was demonstrated.

Vital Alert Announces Strategic Relationship with Federal Resources

The partnership will support the technology leader’s CommPac Radio that addresses communications in complex subterranean environments

Vital Alert (VA), global leader in the utilization of Very Low Frequency (VLF) and magnetic induction technologies, recently announced the establishment of a strategic relationship with Federal Resources (FR) for the distribution of their CommPac Radio terminal. VA’s CommPac provides infrastructure-free communications connectivity Through The Earth (TTE) / Through Barriers without the use of repeaters or wires as well as enables communications utilizing magnetic coupling to existing wires or electrical conductors.

VA has spent the last decade refining, configuring and productizing the CommPac terminal through participation in multiple user demonstrations and exercises; ultimately, improving the product to address difficulties faced while communicating in subterranean or Radio Frequency (RF) denied environments encountered by the military, public safety personnel, first responders and in industrial applications. The CommPac is compatible with existing radio technology utilized in these environments to provide seamless network connectivity ensuring primary and redundant communication capabilities.

FR is a worldwide, leading provider of quality solutions for warfighters and first responders with extensive presence and reach into market areas and existing customers where the CommPac Radio capability is critically applicable and needed. FR has paved the way in the service contract and manufacturing industry.

Michael Homer, CEO of VA, stated, “Leveraging FR’s reputation and distribution reach will expedite familiarizing military and first responders to the unique technical capability of our CommPac Radio and demonstrate how they can immediately employ this equipment to support operations in subterranean environments where traditional radio technology simply cannot function.”

“We are looking forward to sharing this lifesaving technology with our customers,” said Sid Sidebotham, Federal Resources’ Senior Vice President, MRO Market,. “The CommPac radio works in synergy with FR’s product offerings for the subterranean environment and will assist to ensure mission-sensitive information reaches the surface along with increasing a mission’s rate of success.”

In a Second Korean War, U.S. Troops Will Fight Underground

U.S. Army war planners and weapons developers have been increasing efforts to fast-track networking technologies for soldiers operating underground in tunnel complexes and in dense urban environments.

At Vital Alert, we have developed the necessary tools for military and emergency personnel to be able to communicate in almost any environment below ground. The CanaryCommPac is an extremely portable communication terminal that allows service persons to send voice, text and data through rock, soil and concrete for up to 300m below the ground. It can easily be coupled with existing radio devices and is easy to carry and place in different locations.
