Background & Context
Civil Air Patrol conducts inland search-and-rescue for the AFRCC, including:
-
Missing aircraft searches using ELT/PLB signal location
-
Missing-person missions in wilderness, rural, and mountainous areas
-
Post-disaster grid sweeps and damage assessments
-
Coordinated air–ground SAR operations
-
Clue-based search operations using hasty teams and expanding search grids
Field teams commonly encounter terrain that limits traditional communication methods.
What environments do they mostly operate in?
Dense forests, mountain valleys, ravines, rural agricultural areas, and disaster-affected zones. Many SAR missions occur outside of or below cellular and VHF coverage.
Challenges Before SpecFive
-
VHF signals frequently dropped in terrain shadows or heavy vegetation
-
Teams lost contact while contouring slopes or following ELT bearings
-
Command had no real-time view of team movement or progress
-
Reporting clues sometimes required moving to higher terrain or backtracking
Were there specific incidents where lack of reliable communication created risks?
Yes, ground teams tracking ELT signals in deep ravines lost contact during searches. Missing-hiker missions in dense woods often required runners or repositioning vehicles to reestablish communications, slowing mission tempo and increasing risk.
Why was finding a better solution essential?
Real-time information flow is critical in SAR. Communication delays slow evidence exploitation, expand search areas, and reduce rescue efficiency. A resilient mesh network dramatically improves command visibility and team safety.
Adoption & Deployment
Which SpecFive devices they used?
SpecFive Ranger, Ranger Magnum, Voyager, Trekker BRAVO, Trace XR, and the Spec5 Copilot for UAS platforms.
How were these devices integrated into their operations?
-
Rangers were issued to ground team members for continuous GPS location sharing and text communication
-
Voyagers served as vehicle-mounted relay nodes, typically positioned on ridgelines or key terrain to establish a stable mesh footprint
-
Trekker BRAVO units were used by team leaders for durability and extended battery life
-
UAS equipped with the Spec5 Copilot acted as airborne mesh repeaters, providing top-down signal coverage during ISR missions
-
Command staff viewed real-time location history and team positions through ATAK
How easy was setup and training?
Very easy. Devices arrived preconfigured, and users only needed brief familiarization. ATAK integration training was delivered through short in-house sessions and hands-on practice.
What training did your team receive?
Ground teams were taught how to:
-
Pair devices with ATAK
-
View live positions and location history
-
Drop digital clues and grid markers
-
Operate Voyagers as vehicle-based nodes
-
Launch UAS with Copilot modules for airborne mesh coverage
How has your team adapted after training?
SpecFive devices are now standard equipment during SAR missions. Vehicles routinely deploy with Voyagers, and UAS teams stand ready to launch Copilot-equipped drones whenever terrain challenges communication.
Use in the Field
During a missing-hiker search in dense forest with deep valleys, three CAP ground teams conducted adjacent grid sweeps. A Voyager-equipped CAP vehicle was positioned on a ridge as a fixed mesh anchor, while a UAS with a Copilot orbited above the valley, creating a flying mesh repeater.
Key impacts:
-
Ground Team 1 located footprints and other indicators and instantly reported them despite being in a VHF dead zone
-
Location history showed that Ground Team 2 drifted out of their assigned grid due to fallen trees; command corrected their route immediately
-
No team ever lost connectivity thanks to the combined ground and airborne mesh coverage
-
Air and ground coordination through ATAK allowed instant map updates, clue-sharing, and reallocation of search resources
How did the devices improve coordination, safety, and response times?
-
Airborne Copilot nodes eliminated blind spots
-
Voyagers created a stable, predictable communication hub
-
Real-time location history showed grid coverage progress and prevented overlapping effort
-
Command identified unexpected stops or deviations instantly, improving safety
Did they use GPS location sharing, mesh relays, or ATAK integration? If yes, how did they help?
Yes—GPS location sharing created a live movement trail for each team, mesh relays extended coverage through difficult terrain, and ATAK provided a unified operational picture for command, aircrews, and ground teams.
Results & Impact
-
Dramatic reduction in lost-communication incidents
-
Faster response to clues and discoveries
-
Improved grid completion accuracy through visible location history
-
Increased operational tempo through immediate decision-making
-
Higher confidence in team safety and situational awareness
Command now maintains continuous visibility of field team movements, enabling faster, safer, and more efficient SAR operations. Location history has become invaluable in verifying coverage for AFRCC mission documentation.
Mesh communication removes the need for satellite phones, portable repeaters, or cellular service subscriptions, significantly reducing operational costs.
Future Outlook
Teams appreciate the reliability, the simplicity of Rangers, the strong performance of Voyager vehicle nodes, and the unique advantage of the Copilot-equipped UAS acting as airborne mesh repeaters. Operators also value ATAK’s clean visualization of real-time location history.
Would you recommend SpecFive devices to other Civil Patrol or emergency response units? Why?
Absolutely. The combination of ground nodes, vehicle nodes, and airborne mesh repeaters creates a highly resilient communication system that dramatically improves mission coordination and safety.
Do you plan to expand the use of SpecFive devices in future operations?
Yes—CAP intends to increase the number of Voyager-equipped vehicles and Copilot-equipped UAS and integrate mesh networking into more SAR and disaster deployments.
Are there any features or improvements you would like to see in future versions?
Desired enhancements include longer battery life, improved weatherproofing, and even deeper ATAK integration, including direct mission package synchronization.
