The PROWLER geosynchronous SIGINT geolocation platform was initially intended to help locate strategic relocatable targets. The design of this spacecraft is said to include low-observable features.

PROWLER was an antecedent of the Precision SIGINT Targeting System (PSTS) Advanced Concept Technology Demonstration [ACTD]. Apart from the Army RC-12 Guardrail's Communications High-Accuracy Location System (CHALS) and Quicklook ES systems use of time-difference-of-arrival direction-finding, few existing SIGINT systems provide targetable geolocation accuracies against communications or radar emitters. PSTS is a Joint Service and Defense Agency effort to develop and demonstrate a near-real-time, precision targeting, sensor-to-shooter capability using existing national [including overhead] and tactical systems. PSTS will provide tactical users with targeting that is one order of magnitude improvement over what can be accomplished by any of the single candidate systems operating alone.
