The IMPLS Launch Systems HPR-III (HPR THREE) is a single pad controller with a wired console and 100, or 300 ft. extension to connect the controller to the console. It requires a 12v battery connected to the controller at the pad.

The HPR-III provides audible continuity test at the pads and console. A console key switch locks out arming the system. An arm switch on the controller must be switched to Arm to allow arming the controller from the console. When armed, the controller sounds a LOUD siren to warn of Arm condition. Arm may be dropped at the controller by flipping the Arm switch to Safe.

The controller is built into a wire spool so that the ethernet, launch leads, and battery connector may be spooled into one neat package. 

  • The launch leads and cable wind onto the pad-side spool (Controller).

  • Full size heavy duty igniter clips are suitable for MPR and HPR ignitors.

  • Check continuity at the controller and at the console. A loud piezo buzzer indicates good continuity.

  • When armed, a siren sounds so that everyone is aware that a launch is about to happen.

  • The controller includes a 10 amp thermal circuit breaker in case of a short circuit.


Clean and simple. Easy setup, operation, and tear down. All components fit together on the field and in storage too. No loose parts means no disappointments.
