Hermes: A Telemetry & Command Framework and Development Environment

[Kronos3]

Hello F Prime community,

I am excited to announce the initial public release of Hermes, a previously JPL internal tool (aka RSVP Lite) used on a number of JPL flight projects and technology developments internally. This software is a set of VSCode extensions to help operate spacecraft in realtime and can be used during development and operations. If you enjoy using the VSCode FPP extension, this tool was developed by the same author.

The tool is very versatile and can interface with a number of external tools such as Grafana, OpenTelemetry compatible databases, InfluxDB, TimescaleDB, and Clickhouse.

Here's a sneek peek of the VSCode-based user interface. This allows command authoring and validation in a Jupyer Notebook style interface, plotting telemetry, viewing events and managing file uplink and downlink.

We've used this tool during the development of CADRE, a lunar rover mission using F Prime. I've included an example of one of part of our dashboard displaying 2D drive information over one of our drive legs during testing.

I'd love to get feedback from teams inside and external to JPL on this software so feel free to open issues in the repository (or comment on this discussion) on anything from bugs, usability, recommendations, or questions.

Warning

The documentation is still in the works though there should be enough to get started and working with your current F Prime deployments.

Very cool! The dashboard you showed looks like it's from Grafana. Is that integrated into Hermes?

Yes, it pushes to an external DB (many supported) which we query through Grafana. This screenshot was from a CADRE dashboard.
