Ground Support Equipment Tracking for MRO

Ground Support Equipment Tracking: Do You Need More GSE or Better Visibility?

When a maintenance team cannot find a ground power unit, access stand, jack, trolley, or test cart, the immediate conclusion may be that the site does not own enough equipment.

That conclusion can lead to another purchase.

The new equipment enters the same operation, follows the same informal allocation process, and may become just as difficult to find as the existing fleet.

In many aircraft MRO facilities, the problem is not only the number of assets. It is the lack of reliable information about location, availability, assignment, condition, and use.

Ground support equipment tracking allows the MRO provider to measure those factors before increasing the fleet.

What counts as ground support equipment in MRO?

Ground support equipment, or GSE, includes the vehicles, machines, stands, carts, and support assets used to service, move, test, access, and maintain aircraft.

IATA describes GSE as necessary for the safe and efficient operation of airports and aircraft servicing. Ground operations standards also cover GSE management, functional requirements, maintenance, safety, and training.

Within an MRO environment, tracked equipment might include:

• Ground power units
• Air-start units
• Hydraulic power units
• Nitrogen and oxygen carts
• Aircraft jacks
• Tow tractors and tugs
• Maintenance stands and platforms
• Engine stands
• Wheel and brake trolleys
• Mobile test equipment
• Tool carts
• Workstations
• Portable lighting
• Lifting equipment
• Component transport frames

Some units operate mainly inside a hangar. Others move between workshops, aprons, aircraft stands, stores, and outside storage areas.

This mix makes one tracking method unlikely to suit every asset.

Location does not always mean availability

Knowing where a unit is provides only part of the answer.

An item of GSE may appear on a map but still be unavailable because it is:

• Assigned to another aircraft
• Under maintenance
• Awaiting inspection
• Unserviceable
• Reserved for a later task
• In the wrong configuration
• Missing an attachment or cable
• Suitable for a different aircraft type
• Blocked behind other equipment
• Parked in a restricted area

A useful ground support equipment tracking system must connect location with status.

The technician should be able to search for the nearest suitable and serviceable unit, not merely the nearest unit of the same category.

Why manual GSE allocation breaks down

A small maintenance operation may manage shared equipment through radio calls, whiteboards, spreadsheets, or supervisor knowledge.

This can work while the equipment fleet, site, and number of work packages remain small.

The process becomes harder when:

• Several aircraft occupy the hangar.
• Multiple shifts share equipment.
• Assets move between indoor and outdoor areas.
• Different departments own similar units.
• Work priorities change during the shift.
• Equipment remains beside an aircraft after use.
• Contractors and customer teams share the site.
• Technicians borrow units without updating the allocation record.

The equipment is not necessarily lost. It has moved outside the information process.

RTLS maintains a location record as the equipment moves, reducing dependence on manual updates.

Track GSE across indoor and outdoor operations

Aircraft MRO sites present a mixed location environment.

GPS and GNSS work well for vehicles and mobile equipment across aprons, yards, roads, and outside storage areas. Satellite signals provide less reliable indoor positioning within hangars and workshops.

BLE can provide zone-level tracking inside facilities. It can show that an asset is in a hangar, aircraft bay, workshop, or equipment area.

UWB can provide higher accuracy where the MRO provider needs to distinguish equipment positioned around an aircraft, between workstations, or within a controlled area.

RFID readers can record equipment passing through doors, gates, or issue points.

A combined system can maintain one asset identity while the positioning technology changes between environments. The operator sees the equipment within the same application rather than switching between an indoor system and a separate vehicle-tracking platform.

Measure dwell time and idle time

Finding equipment solves an immediate problem. Utilization data addresses the cause.

An asset may spend long periods:

• Parked beside a completed aircraft
• Waiting in a staging area
• Allocated but unused
• Moving between distant storage areas
• Held by one department
• Waiting for cleaning or inspection
• Under repair
• In a location where another team cannot access it

RTLS records how long the equipment remains in each zone.

This creates a more useful view of utilization than a simple “in use” or “available” field.

An item assigned to an aircraft for eight hours may only support work for part of that time. The remaining period may represent staging, waiting, poor collection, or an allocation rule that needs review.

Managers can use these records to compare:

• Productive time
• Allocated time
• Idle time
• Maintenance time
• Travel time
• Time outside the assigned zone
• Demand by aircraft bay or work package

This provides evidence for equipment purchases, fleet reduction, maintenance scheduling, and allocation changes.

Connect location to equipment serviceability

EASA ground-handling guidance requires organizations to follow vehicle and equipment maintenance schedules and conduct serviceability checks. It also states that GSE approaching aircraft should be serviceable and positioned according to relevant operational procedures.

A location system does not perform the serviceability check. It can connect the check result to the equipment’s identity and current location.

This can support rules such as:

• Prevent an unserviceable unit from appearing as available.
• Alert when equipment awaiting maintenance leaves the repair zone.
• Notify the maintenance team when a unit reaches its service interval.
• Show the nearest approved unit for a task.
• Record when a unit enters and leaves the maintenance workshop.
• Direct returned equipment to inspection before reallocation.

The system can also maintain digital records for attachments, aircraft compatibility, operator requirements, and inspection dates.

Use geofences to improve equipment control

A geofence is a digital boundary placed around a physical area on the facility map.

For GSE, geofences can represent:

• Aircraft bays
• Equipment parking areas
• Workshops
• Charging zones
• Fuel areas
• Restricted aircraft zones
• Apron sectors
• Maintenance areas
• Indoor and outdoor storage

Rules can then respond when tracked equipment enters, leaves, or remains inside those zones.

For example, the platform may alert when:

• Equipment leaves its permitted operating area.
• A unit remains beside an aircraft after the work package closes.
• An electric vehicle does not return to its charging area.
• GSE enters a restricted zone.
• An asset moves to the wrong aircraft bay.
• Equipment remains outside overnight.
• A unit under maintenance leaves the workshop.

These controls do not replace safe driving, guide-person procedures, operator training, or equipment-positioning rules. They provide another source of operational evidence.

Improve equipment allocation

A live equipment view can help supervisors allocate GSE based on current demand rather than ownership or habit.

The allocation process can consider:

• Current location
• Serviceability
• Aircraft compatibility
• Existing assignment
• Travel distance
• Planned task duration
• Predicted demand
• Maintenance schedule
• Battery or fuel status
• Required attachments

This can reduce the practice of teams holding equipment because they do not trust that another unit will be available later.

Better information can support a shared fleet without removing local control over high-risk or specialized assets.

How BlueGPS supports GSE tracking

BlueGPS provides a unified view of indoor and outdoor equipment using location data from BLE, UWB, GPS, RFID, and other tracking systems.

The platform can track GSE, jigs, stands, vehicles, and other shared equipment on a live site map. It can also connect location with asset status, assignment, movement history, work orders, and maintenance information.

BlueGPS supports:

• Live and last-known GSE location
• Search by asset type, ID, status, or assignment
• Indoor and outdoor tracking
• Utilization and dwell-time analysis
• Equipment-zone alerts
• Serviceability and maintenance status
• Allocation across aircraft bays
• Movement and event history
• Integration with maintenance and enterprise systems
• Rules based on presence, movement, and dwell

The platform does not require every equipment type to use the same positioning technology. An MRO provider can combine existing GPS trackers, BLE tags, UWB systems, RFID readers, and mobile devices within a common location layer.

Measure before buying more equipment

A shortage of available GSE may be a fleet-capacity problem.

It may also be an allocation, return, maintenance, or visibility problem.

Before purchasing more equipment, the MRO provider should measure where the existing fleet is, how often it is used, how long it remains allocated, and why it becomes unavailable.

Ground support equipment tracking provides that evidence.

BlueGPS helps maintenance teams locate GSE, connect it to the work plan, and understand whether equipment demand reflects a true shortage or a process that can be improved.
