From the outset the Jaguar was equipped with a navigation and attack system. While A versions had a reliable double gyroscopic system and a [[Doppler radar]] derived from the Mirage IIIE, the GR1s had a totally new digital system with an [[inertial navigation system]] and a [[heads-up display]], plus a Laser Ranging and Marked Targeting System (LRMTS) in the nose. These systems were a step above the current technology of the time, but reliability was quite low.{{Citation needed|date=January 2021}}

There were many more systems added with the time, like the Atlis II in the French aircraft, and, in 1994–95, some GR1s had laser-designator systems fitted. Missiles like [[AS-30]] and the anti-ship [[Sea Eagle (missile)|Sea Eagle]] were added. Some IAF aircraft had the Agave radar system, purposely for maritime strike. India later developed the DARIN system in its Jaguar fleet, with a modern 1553 databus.{{Citation needed|date=January 2021}}

Although in operational theatres such as the [[Gulf War]] the Jaguar proved to be mechanically more reliable than the [[Panavia Tornado]], the aircraft's avionics were a hindrance to conducting missions.<ref name = 'D&C 34'>Donald and Chant 2001, p. 34.</ref> Owing to the Jaguar A's shortcomings in navigation and target acquisition, French Jaguars had to be escorted by Mirage F1CR reconnaissance aircraft to act as guides. The Jaguar provided a valuable component of the campaign; the RAF detachment of 12 Jaguars flew 612 combat sorties, with no aircraft lost.<ref name="WAPJ11 p93">Jackson 1992, p. 93.</ref>

Significant changes were made both during and shortly after the war.<ref name="Barrie"/> Both French and British Jaguars had recently-developed [[Global Positioning System]] (GPS) receivers fitted, more accurate than their previous navigational systems.<ref name = 'R&H 151'>Russell and Hasik 2002, p. 151.</ref> Prior to [[Operation Deliberate Force]], the 1995 NATO bombing campaign in [[Bosnia and Herzegovina]], a dozen Jaguars were upgraded with the capability to carry the [[TIALD]] [[laser designator]] pod and [[British military aircraft designation systems|redesignated]] ''Jaguar GR1B'' or ''T2B'' respectively.<ref name="AI Oct97 p226-8">Lake ''Air International'' October 1997, pp. 226–228.</ref> Shortly afterwards, the RAF upgraded its Jaguar fleet to a common standard, incorporating TIALD and the ability to use new reconnaissance pods. The interim GR3 (''Jaguar 96'') upgrade added a new [[Head-up display|HUD]], a new [[Joystick|hand controller]] and stick top, integrated GPS and [[TERPROM]] Terrain Referenced Navigation.<ref name="Barrie">Barrie ''Flight International'' via ''flightglobal.com,'' 8–14 April 1998, pp. 30–32.</ref><ref name="AI Nov97 p274-6">Lake ''Air International'' November 1997, pp. 274–276.</ref> The further upgraded ''Jaguar GR3A'' introduced the new EO GP1 (JRP) digital reconnaissance pod, a helmet-mounted sight, improved cockpit displays, a datalink, and improved [[Night vision device|night vision goggles]] compatibility.<ref name="AI Dec00 p359-0">Lake ''Air International'' December 2000, pp. 359–360.</ref>
A single Jaguar was converted into the Jaguar Active Control Technology (ACT) with [[fly-by-wire]] controls and aerodynamic alterations to the airframe, allowing aerodynamic instability which improved manoeuvrability, providing data used in the development of the [[Eurofighter]].<ref>[http://www.rafmuseum.org.uk/cosford/collections/aircraft/sepecat-jaguar-act-demonstrator.cfm ''SEPECAT Jaguar ACT Demonstrator.''] {{webarchive|url=https://web.archive.org/web/20110105041649/http://www.rafmuseum.org.uk/cosford/collections/aircraft/sepecat-jaguar-act-demonstrator.cfm |date=5 January 2011 }} ''RAF Museum Cosford.''
