| + | * For a first launch, consider borrowing a known-good tracker from someone else, and adding it to your payload train (i.e. attach it in the line, a few metres above or below your tracker). | ||
| + | * Or make a simple low-power radio beacon (one that just switches on and off every second or so) and attach that - even if your main tracker fails completely you could use direction-finding techniques to locate your flight. | ||

| + | * Note that the predictor does not know the ground height. Predictions will tend to be a few 100m further along than the actual landing. Never rely on a prediction to find the exact payload location, its easy enough to walk past a payload when you know where it is, knowing the location to 100m is as good as lost without a radio | ||
