Vaisala Sigmet Radar and Antenna Control Processor RCP8"

Connecting a weather radar to the outside world
The purpose of a controller is to provide a simple interface between high-level user applications to the various electrical signals that are required to control and monitor a radar and antenna system. The RCP8", our new PCI/Linux based controller, provides the flexibility to connect to radar systems from a variety of manufacturers. With comprehensive BITE monitoring, wide range inputs and programmable control logics, the RCP8" offers outstanding versatility in the field. We provide a fully documented API so that sophisticated users can develop their own application software. Specify the RCP8" for weather radar upgrades or for new weather radar systems. Of course the RCP8" is 100% compatible with the Vaisala Sigmet IRIS software for UNIX workstations.
Flexible algorithms for ground-based and stabilized moving platform applications
The RCP8" implements digital position and velocity servos that are more flexible than traditional analog servos-there are no pots to tweak to tune the servos. Because of the digital approach, the servo feedback can be easily adjusted to stabilize virtually any weather radar antenna system. The RCP8" is so flexible that it is the favorite controller for shipboard weather radar applications since it can connect to an inertial navigation unit and compensate for ship motion to 0.1 degree.
Comprehensive over voltage protection for I/O lines
The Vaisala Sigmet I/O-62 PCI card serves as the gateway for signals in and out of the RCP8". Each I/O line is configured with a fast switching diode to protect it against transient high-voltage spikes from lightning or other sources. This is important since radar systems are often sited in locations that are prone to lightning strikes.
Fail-safe protection for your investment
A radar antenna is a costly item. To protect this investment, the RCP8" provides the most comprehensive fail-safe features in the industry. For example, a watchdog program constantly checks for consistency between the tachometer vs position angles, for velocity over-speed, unresponsive antenna and out of tolerance elevation angles. Aside from these built-in safety checks, the RCP8's" programmable control logics allow users to create their own custom monitoring/response actions (e.g., alarm bells, warning lights, transmitter shutdown, etc.)
