- Topsight E
Topsight E is a helmet-mounted sight (HMD) which displays critical information, protects the pilot, and provides communications. In the display of critical information, Topsight E has three main functions:
*Visual target designation by transmitting the target’s line of sight to the nav/attack system. Used with modern missiles, Topsight allows pilots to perform wide off-boresight target designation.
*Visual target acquisition using reverse cueing mode where the display symbology guides the pilot’s eyes to the target tracked by the aircraft sensors. The nav/attack system provides spatial data.
*Situational awareness based on concise display of vital information (tactical, navigation, safety, etc.).Topsight E has four integrated operational modes:
*Navigation is based on ring laser gyro
INS with embeddedGPS receiver.
*Air-to-air weapon delivery includes guns, rockets and high- and low-drag bombs, using continuous computation of impact point (CCIP) and continuous computation of release point (CCRP).
*Training includes failure simulations, as well as target and threat simulations.*The Topsight HMD was part of the Topflight avionics suite by French Sextant Avionique (with HUD, two MFDs, mission management computer, DMG and LINS) which was part of the so-called "MiG-21UPG" upgrade for
MiG-21 . This upgrade also improved Phazotron radar and Israeli-built DASS and COMMS systems. [ [http://www.vectorsite.net/avmig21_3.html [3.0 Upgrades, Experimentals, & Summary ] ]References
