New blog post: Tooling for CSP. CSP is the cubesat space protocol. It is a network protocol used in cubesat buses, RF communications, and groundstations. Here I showcase some tooling to perform CSP network performance analysis and debugging that I have open sourced. There is a tool called csp-iperf that does throughput testing by using CSP ping packets, and a csp-ping-server that can be used in combination with that tool to reply to these packets.

There is also cspdump, which captures and writes CSP packets to a PCAP file. Finally, a Wireshark dissector allows analyzing CSP and RDP packets (RDP is the reliable data protocol used in CSP for sequence-controlled delivery). Read more: https://destevez.net/2026/01/tooling-for-csp/
