From e9584e846b9bd7926d61451d32ba5d7a30416f7b Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Sun, 10 May 2009 22:58:31 -0700 Subject: [PATCH 1/1] Decrease telemetry rate on the pad to 1/sec instead of 20/sec Transmitting telemetry through the radio consumes a significant amount of battery; reducing the rate to 1/sec will reduce power usage while waiting for launch.
