GPS tracking records may contain coordinates, timestamps, speed or movement information, route histories, and accuracy-related data. A GPS Expert Witness may compare those records with device information, other location evidence, and the conditions under which the position was calculated. The analysis should account for the source, collection method, and technical limitations of the GPS data rather than assuming that every tracking system records location with the same precision.
GPS accuracy can be affected by satellite geometry, signal obstruction, atmospheric conditions, reflected signals, interference, and receiver design or quality. Buildings, bridges, trees, indoor environments, and other surroundings can influence the signals available to a receiver. A GPS Expert Witness may examine positioning records, receiver information, accuracy indicators, and relevant environmental conditions to assess whether the claimed degree of location precision is supported.
GPS expertise focuses primarily on satellite-based positioning, navigation, timing, receiver performance, and how location information is generated. Geographic Information Systems and mapping expertise more broadly address the organization, analysis, display, and relationship of geographic or spatial data. A GPS Expert Witness may evaluate how a reported position was produced, while a GIS, mapping, or surveying expert witness may provide more specialized analysis when the dispute centers on spatial datasets, map construction, surveying, or geospatial relationships.
GPS information can provide position, direction, route progression, speed, and timing data used by a navigation system. Relevant evidence may include recorded coordinates, route histories, timestamps, receiver information, and the mapping or navigation software that used the GPS position. Comparing these sources can help determine whether an apparent navigation problem is associated with the reported position, map data, routing logic, or another component of the navigation system.
Prepares clear, well-supported expert reports outlining methodology, analysis, findings, and opinions.
Provide Deposition Testimony
Explains findings and opinions under oath and responds to questioning during deposition testimony.
Testify in Court
Presents specialized findings and opinions clearly to judges, juries, arbitrators, or other decision-makers.
GPS expertise is generally more appropriate when the central issue involves positioning, tracking, navigation, timing, receiver performance, or interpretation of GPS-derived location information. Satellite or Aerospace Engineering expertise may be more appropriate when the dispute concerns spacecraft design, satellite operations, orbital systems, constellation engineering, or autonomous spacecraft rather than the operation or interpretation of a user's GPS receiver.
