RF TELEMETRY – DGPS, RTK, TIDE

Innerspace engineers have over 30 years experience in RF data transmission. In addition to standard RF products the Models 453A and 453D, custom RF telemetry systems, both short and long range, are regularly quoted. Custom, turn-key telemetry systems are an Innerspace specialty – everything is included for a trouble free installation and operation.
