Luxury Swiss watchmaker Longines is expanding its Sydney presence with the introduction of tracking and timekeeping technology and sponsorship of the Golden Slipper carnival.

The Swiss company will introduce the Longines Positioning System at Saturday's Queen Elizabeth Stakes meeting.

The LPS tracks each horse throughout a race and records individual sectional times registered by 20 antennas around the track.

Juan-Carlos Capelli, the head of international marketing for Longines, said the system was a game changer for the horse racing industry.

"Access to more accurate, flexible data allows you to understand, share and act on the intricacies of performance as never before," Capelli said.

"We are excited to see how the LPS technology can be utilised in the future to improve the experience for racing spectators, TV viewers and even smart phone and tablet users."

The technology boasts accuracy to five centimetres and features 1000 measurements per second.

Leading trainer Peter Moody said the technology would be a valuable asset.

"It will give trainers a guide to the horses competing against their own," he said.

"Any information we can get can only improve racing for the participants and grow our sport."

The data will be shown on the infield screen at Randwick and plans are to make it available on the ATC and Racing NSW websites.

The Australian Turf Club will also introduce the technology at Sydney's other major track, Rosehill, as soon as possible with Canterbury and Warwick Farm to come at a later date.

Rosehill is the home of the $3 million Golden Slipper, the world's richest race for two-year-olds.

Pearce said Longines' sponsorship for the three-week Golden Slipper festival would put further focus on the western Sydney racetrack.

"Longines' partnership of our great race, the Golden Slipper, and Australia's biggest Group One day with five Group One races, is full testament to the regard the racing world has for the race and for Rosehill Gardens," Pearce said.

"Having a global brand such as Longines further elevates the international status of the world's richest race for two-year-old thoroughbreds."
