Expands MPG’s capability in signal processing as demand intensifies for next-generation spectrum monitoring solutions


Espy's teamSENTINEL® family of wideband recording RF sensors is highly configurable to address a wide range of size, weight, power, cost, frequency and coverage requirements. Operators can now conduct signal searches when time permits, with Espy’s extreme recording of wideband digital RF. Signals can be retroactively played back as audio, analyzed to determine signal type, and geo-located on geolocation-enabled sensors.

Espy family offerings include teamSENTINEL®, teamSENTINELmini®, teamSENTINELnano®, teamSOIGNE®, covering ELF, VLF, HF, VHF, UHF and SHF bands.
covering ELF, VLF, HF, VHF, UHF and SHF bands.

Facility, Qualities, & Capabilities

ESPY has several facilities and RF antenna array locations for all design, development, manufacturing and testing requirements to produce the teamSENTINEL family of systems.

Texas: Headquartered on 20 acres of land west of Austin TX that includes an 11,000 square foot facility with an adjacent 4,000 square foot building. The property includes a HF/DF array as well as three V/UHF nodes for testing. There is also a DF calibration table and transmitter on site.

Pennsylvania: A second HF/DF array is in rural eastern Pennsylvania for multi node and remote testing.

Maryland: Satellite office in Columbia MD that has several meeting rooms and workstation for customer training as well as an HF and VUHF system for training and development for multi node and remote operations.





teamSENTINEL© family of wideband recording RF sensors are highly configurable to address a wide range of requirements defined by size, weight, power, cost, frequency coverage (ELF, VLF, HF, VHF, UHF and SHF), wideband recording capacity, signal detection, signal categorization, angle of arrival direction finding (AoA DF) and TNG. Extreme recording of wideband digital RF (hours, days and weeks) affords operators the freedom to conduct signal searches without the pressure of operating in real-time, and all while the system is actively acquiring and recording new RF data. Signals can be retroactively prosecuted interactively by an operator to play back as audio, analyze to determine signal type, and geo-locate on geolocation-enabled sensors.




The teamSOIGNE Client Application Suite is distinguished for its ease-of-use and effectiveness and is specifically designed to eliminate interference in military communications systems. Equipment used in crowded communication bands and closely located transceivers are often needed for simultaneous operations (SIMOP) and require RF systems designers/integrators to pay increasing attention to managing their equipment’s generation and rejection of undesired signals and noise. Receiver desensitization greatly diminishes communications range.




RF Peripherals

A 8-channel, 30-512 MHz RF interference canceller system that achieves 40 dB of strong signal attenuation without the need for reference signals from local transmitters. This enables the reception of low-level RF signals in the presence of up to 8 strong interferers as a result of its inherent low-loss path for all non-cancelled signals. It provides fast canceller acquisition, compatible with SINCGARS and HAVE QUICK hopping waveforms.
