The Path In
Each step stands on its own and adds to the ones before it. The radio firmware costs nothing; the map is a one-time licence; the hardware is yours when you want it.
Step 1 · Free
GridDown Secure Messenger
Encrypted LoRa text, voice, and image messaging with 900 MHz drone scanning and ASTM F3411 Remote ID detection. Free, open-source firmware you flash from your browser onto a handheld radio sold by our affiliate partner. No account, no infrastructure.
Step 2 · The Map
GridDown Maps
Offline tactical mapping and navigation that keeps working with the network off: cached maps, GPS-denied positioning, terrain analysis, RF line-of-sight, and the radio, sensors, and team all on one picture. Delivered at app.blackatlas.tech after purchase.
Step 3 · See More
Sensor Hub — Consumer
Passive, receive-only sensor appliance: aircraft, vessels, drones, emergency beacons, and environmental and safety readings, fused onto GridDown and any TAK client. Bring your own instruments; the hub does the fusing.
Step 4 · Personal
AtlasGuard
Pocket-sized counter-surveillance sensor. Finds hidden trackers, covert cameras, surveillance bugs, rogue cell towers, and GPS jamming — then points you to them. Fully offline, no cloud, no account. Connects to GridDown. Assembled in Virginia.
Step 5 · Coming Soon
AtlasGate Home
An NDAA-compliant home router built for Americans: OpenWrt firmware, WireGuard VPN, network-wide ad blocking, optional cellular failover, and TAK integration. Assembled from allied-nation components and integrated in the US.
Or · Ready Out of the Box

A rugged Samsung Galaxy Tab Active5 Pro with GridDown pre-installed, offline maps already cached for your area, and tested peripheral pairing. Add sensor modules any time.
