Don't get me wrong, this is a cool idea but the main complexity with DAGR is around the SAASM functionality which you can't do on a phone, at least not a publicly available one.
I also agree that you should be able to make a DAGR 2 that is much smaller and more powerful but it would always have to be a standalone device.
Great point — you're absolutely right that SAASM is the critical differentiator, and that's not something any civilian device can replicate. Red Grid MGRS runs on standard L1/L5 GPS, so it doesn't have the anti-spoofing or encrypted PPS capability that makes the DAGR essential in contested environments.
That said, the vast majority of DAGR usage I see isn't in GPS-denied or spoofed environments — it's in land nav training, patrol planning, calling in grids on routine ops, and reporting. For those use cases, a phone with good civilian GPS (3-5m accuracy now with dual-frequency) handles it fine.
I'd love to see a DAGR 2 that's smaller and cheaper while keeping SAASM though...here's to hoping we get more options
