GPS-Based Toll Collection in India — Complete Guide (GNSS Tolling)

India is replacing toll plazas with satellite-based GPS toll collection. Here's everything you need to know about the new GNSS system.

Union Road Transport Minister Nitin Gadkari has announced that India will shift to a GPS-based (GNSS) toll collection system, eliminating the need to stop at toll plazas. The system uses satellite tracking and On-Board Units (OBUs) to charge vehicles based on the actual distance driven on highways — not flat-rate booth charges.

Quick Facts

●Full form: Global Navigation Satellite System (GNSS)
●Announced by: Union Minister Nitin Gadkari
●Target rollout: Nationwide by end of 2026
●OBU device cost: ₹1,000–₹1,500 (expected)
●20 km free per day per direction
●Pilot: NH-275 (Bengaluru–Mysuru) & NH-709 (Panipat–Hisar)
●Replaces: FASTag + toll plazas (phased)
●Savings: ₹1,500 crore/year in fuel

What Is GPS-Based Toll Collection?

GPS-based toll collection (officially called GNSS-based Electronic Toll Collection) uses satellite technology to track a vehicle's movement on national highways and expressways. Instead of stopping at a toll booth, your vehicle's On-Board Unit (OBU) communicates with satellites to record the exact distance you travel. Toll is calculated automatically and deducted from your linked account — no barriers, no queues, no stopping.

How Does the GNSS Toll System Work?

The system has three main components working together:

›On-Board Unit (OBU): A small GPS device installed in your vehicle, similar to a FASTag tag but with satellite tracking capability.
›Satellite Tracking: GNSS satellites (GPS, GLONASS, NavIC) track the OBU's location as the vehicle enters and exits a tolled highway section.
›Central Processing System: The NHAI backend calculates the distance driven, applies the per-kilometre toll rate, and deducts the charge from your linked wallet/account.
›ANPR Cameras: For vehicles without OBU, high-speed Automatic Number Plate Recognition cameras capture the number plate and generate a toll invoice.

The 20 km Free Rule

One of the biggest benefits: under the revised National Highways Fee Rules (September 2024), vehicles using the GNSS system will get zero toll for the first 20 km of highway travel in each direction, once per day. This is a major relief for people living near highways who use them for short daily commutes. Beyond 20 km, toll is charged for the entire distance including the initial 20 km.

What Happens to FASTag?

FASTag will NOT be scrapped overnight. The government has confirmed a hybrid transition period where both systems will run simultaneously:

›Phase 1 (Current): RFID-based FASTag continues at all toll plazas.
›Phase 2 (Transition): ANPR + FASTag hybrid system at select plazas — cameras read number plates, FASTag validates the tag.
›Phase 3 (Full GNSS): OBU-based distance tolling goes live. Toll plazas are gradually removed.
›Vehicles with OBU will get a dedicated fast lane at toll plazas during the transition period.

OBU Device — Price, Installation & Registration

The On-Board Unit is the key hardware for the new system. Here's what we know so far:

›Expected cost: ₹1,000–₹1,500 (one-time, similar to FASTag pricing).
›Installation: At authorised centres (likely at existing FASTag issuance points, petrol pumps, and NHAI offices).
›Linking: The OBU will be linked to your vehicle RC, mobile number, and a payment wallet (bank account / UPI / prepaid wallet).
›For new vehicles: OBU is expected to come pre-installed from the manufacturer (like FASTag is today).
›For old vehicles: Retrofit kits will be available at authorised service centres.

Pilot Projects & Testing

The GNSS toll system has been piloted on two highway stretches in India:

›Bengaluru–Mysuru section of NH-275 (Karnataka) — one of India's busiest expressway corridors.
›Panipat–Hisar section of NH-709 (Haryana) — a key north Indian highway.
›Delhi–Mumbai Expressway and Bengaluru–Mysuru Expressway are planned for early full-scale deployment.

Rollout Timeline

Minister Nitin Gadkari has stated the GNSS toll system will be implemented nationwide by the end of 2026. However, the Ministry clarified in April 2025 that there is no decision for a nationwide launch from May 1, 2025 — the rollout will be phased:

›April 2025: ANPR-FASTag hybrid pilot at select toll plazas.
›Mid 2025: GNSS pilot expansion to ~2,000 km of highways.
›Late 2025–2026: Trucks and buses first to adopt OBU (commercial fleet).
›End of 2026: Target for nationwide GNSS toll coverage across all NHAI highways.
›2026–27: Private vehicles fully transition; toll plazas gradually decommissioned.

Benefits of GPS Toll vs Current System

The shift from booth-based to satellite-based tolling brings major advantages:

›Zero wait time: No queues, no barriers — vehicles don't stop at all.
›Pay for what you use: Distance-based charging is fairer than flat-rate booth charges.
›20 km free daily: Short-distance highway users near toll plazas benefit significantly.
›Fuel savings: Government estimates ₹1,500 crore annual fuel savings from eliminating idling at toll queues.
›Revenue increase: NHAI expects ₹6,000 crore additional revenue from reduced toll evasion.
›Pollution reduction: Less idling = lower vehicle emissions near toll areas.
›Accident reduction: Toll plaza areas are accident hotspots due to sudden braking — removing plazas improves safety.

What If You Don't Have an OBU?

During the transition, vehicles without an OBU will still be tolled using ANPR (Automatic Number Plate Recognition) cameras installed on highways. The camera captures your number plate, matches it with the VAHAN database, and generates a toll invoice linked to your vehicle. You'll receive the invoice digitally and must pay within the stipulated time, failing which penalties apply.

Frequently Asked Questions

What is GPS-based toll collection in India?

GPS-based toll collection (GNSS tolling) uses satellite technology and an On-Board Unit (OBU) in your vehicle to track highway distance and charge toll automatically — no stopping at toll plazas.

When will GPS toll collection start in India?

Minister Nitin Gadkari has set a target of nationwide implementation by end of 2026. Pilot projects are running on Bengaluru–Mysuru (NH-275) and Panipat–Hisar (NH-709) highways.

Is the first 20 km of highway travel free with GPS toll?

Yes. Under the revised National Highways Fee Rules (Sept 2024), GNSS-equipped vehicles get zero toll for the first 20 km per direction, once per day.

Will FASTag stop working when GPS toll comes?

No. FASTag and GPS toll will run simultaneously during a transition period. Keep your FASTag active until the government officially mandates OBU.

How much does the GPS toll OBU device cost?

The OBU is expected to cost ₹1,000–₹1,500 as a one-time purchase, similar to FASTag pricing.

What happens if I don't have an OBU?

ANPR (Automatic Number Plate Recognition) cameras will capture your number plate and generate a toll invoice. However, you won't get the 20 km free benefit.
