The short version

  • Each has a real cost: Correlator3D the standard licence caps at 61 megapixel sensors, so an operator moving to a medium or large format camera has to buy a different and separately quoted licence rather than paying an upgrade fee.; GPS Trackit month-to-month pricing carries a premium, so measured across three years the total cost usually exceeds a competitor with hardware amortised into a term contract.
  • They diverge on capability: Correlator3D covers Aerial triangulation, GPS Trackit covers Live tracking.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Correlator3D

  • An aerial survey company processing large photographic blocks where per-project cloud credits would be more expensive than owning a licencenot GPS Trackit
  • A national or regional mapping agency that needs software it can run offline on classified or restricted imagerynot GPS Trackit
  • A drone service provider producing bare-earth terrain models for volumetrics and corridor mapping at high throughputnot GPS Trackit
  • An organisation that wants a perpetual licence because a multi-year subscription cannot be justified against its capital budgeting rulesnot GPS Trackit

GPS Trackit

  • A contractor whose fleet size swings with the season and who cannot justify a three-year commitment on vehicles it may not run next springnot Correlator3D
  • A small service business trialling telematics for the first time that wants an exit if drivers or supervisors do not adopt itnot Correlator3D
  • A fleet that needs devices fitted the week they arrive, without booking installation appointments across a depotnot Correlator3D
  • An operator replacing a vendor mid-contract that wants a stopgap platform rather than another long agreementnot Correlator3D

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Correlator3D

  • The standard licence caps at 61 megapixel sensors, so an operator moving to a medium or large format camera has to buy a different and separately quoted licence rather than paying an upgrade fee.
  • It is Windows desktop only with no cloud processing option, so throughput is bounded by the workstation and GPU you buy, and there is no way to burst capacity for one large job.
  • There is no collaboration layer, client portal or field application, so deliverable sharing, review and version control all have to be handled by other software.
  • The interface and workflow are built for photogrammetry specialists; an occasional drone operator will find the learning curve steeper than a consumer-oriented mapping package.
  • The perpetual licence includes only one year of support and updates, and staying current afterwards means paying maintenance, so the headline $5,900 is not the whole long-term cost.

GPS Trackit

  • Month-to-month pricing carries a premium, so measured across three years the total cost usually exceeds a competitor with hardware amortised into a term contract.
  • The feature set is tracking-first, with a shallow maintenance module and no meaningful work order, parts or inventory management, so fleets serious about maintenance need a second system.
  • Compliance tooling is basic, and a fleet that takes on regulated interstate work will find the hours of service capability behind vendors built around the mandate.
  • The integration list is short and the API is limited, so pushing telematics data into payroll, job costing or an ERP normally becomes a manual export routine.
  • Self-installed OBD-II devices are easy to fit and equally easy for a driver to unplug, and the tamper reporting does not make up for the fact that the physical device is within reach of the person being monitored.

Answered from the vendors’ own pages

Correlator3D: Can I still buy a perpetual licence?

Yes. $5,900 for a permanent licence and $6,400 for a permanent floating licence, each including a year of support and updates.

GPS Trackit: Is there really no contract?

The subscription is month to month, but read the hardware terms. Devices are supplied on the expectation they come back, and unreturned units are charged for.

Correlator3D: What limits the standard licence?

Sensor resolution, up to 61 megapixels. Medium format, large format and satellite imagery need separately priced licences.

GPS Trackit: How does the cost compare to Samsara or Verizon Connect over three years?

Generally higher per vehicle, because those vendors discount in exchange for the commitment. The comparison only favours GPS Trackit if you value the ability to leave.

Correlator3D: Is there a cloud version?

No. Processing runs on your own Windows workstation. SimActive offers a data processing service as an alternative to buying the software.

GPS Trackit: Can drivers unplug the tracker?

A plug-in OBD-II device can be removed in seconds. The system reports the disconnection, but enforcement is a management problem, not a technical one. Hardwired units are available for fleets where this matters.

Correlator3D: Does it handle satellite imagery?

Yes, under a separate satellite licence class quoted on request.
