Inertial Aerosystems is introducing a new range of low-cost dual-channel PC104-compliant synchro/resolver output cards. The PC104-DS series cards are manufactured by USA-based Computer Conversions and are designed to provide precision simulated AC synchro and resolver formatted signals for use in navigation and positioning systems. These cards can also be used with test sets for both industrial and COTS military applications or combined with synchro amplifiers for torque receiver applications.
All models provide 16-bit resolution and selectable accuracy grades from +/-4 arc-minutes to +/-30 arc-seconds. They are described by Inertial Aerosystems as "virtually indestructible" with transformer isolation, protection against thermal shocks, transients and short circuits.
Featuring a wide band frequency of DC-10,000Hz, and a COTS operating temperature range of -45 to +85degC, these cards are suitable for upgrading legacy equipment as well as new applications. The use of internal isolation transformers on the reference inputs provides phasing flexibility and immunity from ground loops or ground reference-induced noise. It is an effective barrier to prevent any electrical noise on the reference source input from affecting the user's digital control system.
The PC104-DS range can be populated with up to four different styles of output converter.
These versatile synchro/resolver output cards are suitable for use where space and weight are at a premium, including GPS applications, head-up display (HUD) systems, field test equipment, mobile antennae, and air and nautical navigation aids.
