Looking for a long term real time tracking technology for monitoring big game in South Africa

We currently use handheld radio telemetry, however for the amount of individuals we want to monitor it is not possible to continue this way. If anyone has knowledge of, or has designed a system they would like to test which would enable us to constantly get location data from a large set of animals within a large reserve I  would love to hear from you.
