CONTROLLED POSITIONING
04Anchor every observation to a reliable reference.
RTK and PPK positioning strategies connect aerial and ground observations to the project coordinate system with a documented control and check process.
Discuss this serviceWHAT IT SOLVES

TYPICAL APPLICATIONS
Establish and document reference points for aerial mapping, construction and repeat observations.
Support consistent positioning across roads, railways, utilities and other extended project areas.
Use post-processed correction where real-time communication is unreliable or unsuitable.
DELIVERY WORKFLOW
Confirm coordinate system, known control, accuracy need and site constraints.
Set the base, correction source, control and independent check method.
Record field and mission positioning data with complete survey notes.
Process corrections, compare checks and issue the positioning record.
DELIVERABLES
The control schedule lists the reference points used to connect survey observations to the project coordinate system. It records each point's identifier, coordinates, description and relevant field notes so it can be understood or revisited. This schedule gives aerial, ground, CAD and GIS teams a common positioning basis and supports repeatable work when later surveys or construction activities need to use the same control framework.
The checkpoint record documents observations that were kept independent from the main processing control and used to review the resulting position. It compares the surveyed output with known check locations and records the differences found. This provides a transparent quality check, helping users understand whether the positioning process supports the agreed purpose without presenting a precision claim that is not supported by the collected evidence.
The correction record explains how positioning corrections were obtained and applied during RTK or PPK processing. It can include the base or network source, observation timing, equipment references, processing approach and relevant field conditions. Keeping this information with the survey makes the positioning workflow traceable and helps technical users understand how raw receiver observations became the coordinates used by the delivered mapping and models.
A coordinate schedule provides the verified project points in formats that can move directly into spreadsheets, CAD or GIS software. Each point is supplied with a clear identifier and the appropriate coordinate and level fields. The schedule reduces manual transcription, supports setting-out or review workflows and gives different project teams a consistent list of positions tied to the stated coordinate reference and survey basis.
Georeferenced outputs are survey images, models or spatial layers aligned to the confirmed project coordinate system. This alignment allows them to overlay correctly with design drawings, asset information, land data and later survey records. The delivery identifies the reference system and units so users can place the files accurately in their working environment and avoid shifts caused by missing or misunderstood coordinate information.
The accuracy statement summarises the positioning method, control used, independent checks and review results relevant to the delivered data. It explains the basis on which the outputs should be used and records any limitations identified during processing. Rather than offering a generic guarantee, it gives engineers and GIS users a concise, evidence-based account of the survey's positional quality for the agreed project purpose.
