SAE J2520-2026 Classification, Nomenclature, and Specification Definitions for Directional Drilling Tracking Equipment

SAE J2520-2026 defines terminology and commercial specification guidelines for directional drilling tracking transmitters, receivers, telemetry devices, and remote displays.

SAE J2520 FEB2026 establishes common terminology, nomenclature, and commercial specification guidelines for electronic tracking equipment used in horizontal directional drilling and horizontal earthboring operations. The standard covers tracking transmitters, tracking receivers, telemetry devices, and remote displays. It defines terms related to bore paths, tracking measurements, steering, telemetry, operating ranges, update rates, accuracy, battery life, dimensions, temperature limits, and annular drilling fluid pressure. It also specifies test and reporting conditions for transmitter and receiver performance, telemetry characteristics, and remote display capabilities. This revision was issued in February 2026 and supersedes SAE J2520 JAN2013, with references updated to include ISO 21467:2023.

Application Scope: Applicable to manufacturers, engineers, contractors, and equipment users involved in horizontal directional drilling tracking systems and horizontal earthboring machinery.
