Athletics Technology Stack: Photo Finish, Wind Gauges, False Start and Field Event Measurement

What an athletics meet actually needs

Track and field is one of the most equipment-intensive sports to run because rules from World Athletics (Technical Rules and the C2.1 Equipment specifications) effectively dictate the hardware. A single sanctioned meet needs synchronised timing on the track, a separate distance-measurement workflow for horizontal jumps and throws, vertical event signalling for high jump and pole vault, and a results pipeline that can publish official marks within minutes.

Most national federations approve FinishLynx (Lynx System Developers, USA) for photo finish and a Meet Management System such as RaceResults 12, Athletic.net Meet Manager, or HyTek Meet Manager. ProTSR builds its athletics deployments around FinishLynx and RaceResults 12 because they are accepted by World Athletics for record purposes when configured correctly.

Photo finish and timing

A modern photo finish chain is a line-scan camera (FinishLynx Vision, EtherLynx PRO or Fusion Sport), a gigabit Ethernet link, and the FinishLynx capture/evaluation software. The camera scans the finish line plane at up to 20,000 frames per second, producing an image where time is the X axis. The chief photo finish judge then 'reads' lane-by-lane positions to extract official times to 1/1000 of a second (rounded per Rule 19).

• Camera: FinishLynx EtherLynx PRO or Vision (1000-3000 fps for school meets, 10000+ fps for national/elite meets)
• Start detection: Lynx Start System or Seiko/ReacTime block sensors for false start, integrated into the FinishLynx capture
• Wind gauge: Lynx Wind Gauge or Gill ultrasonic, mounted 50m from finish per Rule 17
• Display: Lynx ResulTV pushing 'last race' graphics to LED or IPTV; FieldLynx tablets at horizontal events

Field events: LaserLynx, wind, vertical signals

Long jump, triple jump, shot put, discus, hammer and javelin can be measured electronically with the LaserLynx Total Station / EDM (Electronic Distance Measurement). Two operators acquire the landing point with a reflective prism and the distance is sent over wireless to FieldLynx tablets, then merged into FinishLynx results. This eliminates the tape-pulling crew and dramatically speeds up the announce-to-results loop.

High jump and pole vault need vertical signal lights (red/white/yellow) at the official's table so judges can show valid attempt, foul, or pass without paper cards. Wind gauges are mandatory for horizontal jumps and sprints up to 200m, with readings printed onto the result.

Displays, web results and notifications

Trackside, you typically need at least one giant LED for start list / current result and a smaller timer display at the finish. Lynx ResulTV pushes the 'now showing' graphic via NDI or SDI; the same feed is sent to a Blackmagic ATEM switcher for broadcast. Live web results are usually pushed by RaceResults 12 to a static results portal (often hosted on the federation domain or on protsr.in), with optional WhatsApp / push notifications to athletes and coaches when their event is heat-listed or a result is final.

Broadcast graphics & venue branding

Broadcast graphics typically include lower-thirds for athlete names and bios, an on-screen scoreboard or 'bug' fed live from the scoring system, dynamic start lists, results pages, head-to-head comparisons, sponsor bumpers, replay wipes, and end-of-session summary cards. Output is usually delivered over SDI from a graphics engine (vMix, Singular.live, CasparCG, or a federation-supplied template pack) into the ATEM or production switcher.

For athletics specifically, you also need event-by-event start lists with seasonal bests, a running scoreboard for combined events (decathlon/heptathlon), and a wind-reading overlay. Venue branding usually covers the start arch, finish gantry, infield sponsor boards, podium backdrop, and bib numbers — all colour-matched to federation guidelines.
