The preliminary packet forwarder utilizes a BeagleBone Black platform to create a one-way broadcast of a Masten RLV’s telemetry stream onto a dedicated payload network that ensures that hosted technologies are isolated from the vehicle network. Using the packet forwarder, real-time data such as GPS location, inertial data, and vehicle state information can be streamed to hosted technologies during an actual RLV flight. In addition to the packet forwarding, payloads can be remotely powered on and off via BeagleBone Black control of a dedicated payload relay board . Including the BeagleBone Black, the preliminary configuration of the Prometheus system will support Raspberry Pi and Arduino platforms.</span></blockquote>
<div><br></div><div>And from the project manager, Scott Nietfeld (in response to being asked on the packet forwarder on the rates and guarantees of real-time data):</div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">

As a result of how the data will be forwarded we cannot make any hard or even soft real-time guarantees; however, in practice the arrival rate should be reasonably consistent. We do expect to use UDP for telemetry forwarding, so your payload would need to be robust enough to tolerate the occasional dropped packet as delivery is not guaranteed.</span> </blockquote>

</div><p>You'd need to make an isolated flight data recorder. Due to the restriction on transmitters, you can only download your data off a shore connection when the vehicle is back on the ground.</p><span><font color="#888888">

The project is for the rapid, streamlined development of tools relating to; visual navigation, landing detection, mass estimation and position/attitude estimation.

>>>> the Masten Team has also been thinking about ways we could engage the broader community and increase accessibility to our VTVL vehicles. One of the largest barriers to entry for any technology developer seeking to conduct aerospace flight testing is access to a vehicle. Limited access to an integrated GPS/IMU navigation system, flight-rated computing platforms, and sensors present additional challenges to innovators. In the spirit of broadening access to aerospace resources, we have had a project cooking in the background called Prometheus.<br>

>>>> Project Prometheus is a Masten program designed to foster the development of flight-test ready technologies by innovators in academic and research settings. By implementing a standardized interface between Masten vehicles and experimental software and hardware tools, Prometheus will provide a streamlined, efficient path for technology maturation throughout the course of tool conception, development and flight test. Access to uniform, flight-tested hardware and software development framework for innovators will ultimately reduce integration, development and other flight test costs.<br>
