LS-28-DRSM “P1 version”, as seen in July 2019 issue of Aerospace Testing International magazine.
This is a very popular configuration of the Modular LS-28-DRSM. We call it the “P1 version”….Portable, Lunchbox. It’s also available in Modular (4x6x1.7 inches) and 1U Rack Chassis configuration.
Once again, a complete Telemetry System that you can carry on and stow in the overhead bins of your flight.
