# Specification

<mark style="color:$success;">**TACSDR**</mark> is a <mark style="color:$success;">**TAC**</mark>**tical&#x20;**<mark style="color:$success;">**S**</mark>**oftware-**<mark style="color:$success;">**D**</mark>**efined&#x20;**<mark style="color:$success;">**R**</mark>**adio** built for the modern tactical mission. Its software-defined architecture makes it the world’s first and only handheld used for communication, signal intelligence and spatial sensing purposes.

{% hint style="success" icon="hands-clapping" %}
This specification is focused on TACSDR's communications capabilities
{% endhint %}

TACSDR delivers voice, video, and high-speed data in a compact, highly portable handheld platform. Using a Linux-processor and [AllSeeing's software-defined radio architecture](https://www.allseeingtech.ca/), it supports ad-hoc, self-forming, and adaptive networking for dismounted users on the move. Its software-driven design allows the system to be upgraded and reconfigured as mission requirements, waveforms, and communication needs evolve.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://tacsdr-docs.allseeingtech.ca/spec/specification.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
