From May 1, GNSS Will Replace Fastag – How New Toll System Works, Charges & Benefits Explained

GNSS Toll Connection : India is all set to roll out a groundbreaking change in its toll collection system. Starting May 1, 2025, the current FASTag system will be gradually replaced with the new Global Navigation Satellite System (GNSS)-based tolling method. The move is aimed at improving efficiency, reducing congestion, and enhancing transparency in toll payments across the country’s highways. But how exactly does the GNSS toll system work? What are its charges, and how will it benefit you?

In this article, we break down everything you need to know about the new GNSS-based toll system that’s set to change the way India travels.

What Is GNSS-Based Toll Collection?

GNSS (Global Navigation Satellite System) is a satellite-based tolling technology that enables automatic deduction of toll charges based on the exact distance traveled on a highway, eliminating the need for physical toll booths or RFID-based scanners like FASTag.

Key Highlights:

• GNSS uses satellite signals to track vehicle movement on toll roads.
• Charges are distance-based, not entry/exit point-based like FASTag.
• Works via onboard devices installed in vehicles.
• Toll deductions are automatic and seamless.

Why Is GNSS Replacing FASTag?

While FASTag did revolutionize toll collection, it had several limitations:

• Vehicles still needed to slow down or stop at toll plazas.
• RFID tags sometimes failed to scan.
• Toll charges were fixed for a stretch, irrespective of actual distance traveled.

GNSS overcomes these challenges by offering a fully automated and more precise tolling system.

Comparison: FASTag vs GNSS

Feature	FASTag	GNSS-Based Tolling
Technology	RFID-Based	Satellite-Based (GNSS)
Toll Calculation	Fixed per toll point	Based on distance traveled
Physical Toll Booth	Required	Not required
Vehicle Movement	Must slow down/stop	Free-flowing
Infrastructure	Needs dedicated lanes, sensors	Satellite tracking only
Tag/Device Requirement	RFID Tag	GNSS Onboard Unit (OBU)
Error Rate	Moderate	Low
Implementation Cost	Moderate	Higher (initially)

How Will GNSS Tolling Work?

The GNSS tolling system will operate via a device called the Onboard Unit (OBU), which will be installed in your vehicle. This device will:

• Track your vehicle’s exact entry and exit on toll highways.
• Calculate the toll fee based on the distance traveled.
• Automatically deduct the toll amount from your linked account.

The system will be connected to a central server monitored by the National Highways Authority of India (NHAI) and other stakeholders.

Steps for Users:

• Register your vehicle with the GNSS system.
• Install the OBU in your vehicle.
• Link your payment method or wallet.
• Travel freely – the toll will be deducted based on distance covered.

GNSS Toll Charges and Cost Benefits

Unlike FASTag, which has fixed rates for toll stretches, GNSS ensures you pay exactly for the kilometers you use on a highway.

Sample Toll Charges (Approx.)

Highway Section	Distance (km)	FASTag Fixed Toll	GNSS-Based Toll (₹1.5/km)
Delhi to Agra (Yamuna)	165 km	₹360	₹247.5
Mumbai to Pune	94 km	₹270	₹141
Bengaluru to Mysuru	118 km	₹135	₹177
Jaipur to Delhi	275 km	₹415	₹412.5
Chennai to Bengaluru	330 km	₹495	₹495
Hyderabad to Vijayawada	273 km	₹315	₹409.5
Lucknow to Kanpur	81 km	₹100	₹121.5

Note: Rates may vary based on the final government-approved price per kilometer.

Benefits for Commuters:

• Pay-as-you-use model saves money for short-distance travelers.
• Zero need to stop at toll booths.
• Less time spent on highways due to reduced congestion.
• More transparency in toll charges.

Implementation Timeline and Rollout Plan

The government has planned a phase-wise rollout of GNSS across India starting May 1, 2025. Initially, it will be:

• Implemented on pilot routes like Delhi-Mumbai Expressway and Bengaluru-Mysuru Corridor.
• Mandatory only for commercial vehicles in the first phase.
• Voluntary for private vehicles for the initial few months.

By 2026, the system is expected to become mandatory for all vehicles, replacing FASTag entirely.

Rollout Timeline:

Phase	Target Group	Areas Covered	Status
Phase 1	Commercial Vehicles	Selected Expressways	May 2025
Phase 2	Voluntary for Private	Metro Corridors	June–Aug 2025
Phase 3	All Vehicles	PAN India – All NH Corridors	By April 2026

How to Get the GNSS OBU Installed?

The government will work with automobile manufacturers and authorized vendors to ensure smooth installation of OBUs.

Installation Process:

• Visit an authorized GNSS installation center or service provider.
• Submit your vehicle documents.
• Pay a one-time device and setup fee (expected ₹1000–₹1500).
• Device will be activated and linked with your payment account.

The OBU will be mandatory for commercial vehicles from May 1, 2025, and for private vehicles later based on the rollout.

Key Advantages of GNSS-Based Tolling

The shift from FASTag to GNSS is more than just a technology upgrade—it represents a step forward in India’s vision for smart transportation and seamless mobility.

Major Benefits:

• Accurate Tolling: Pay only for the road you actually use.
• Reduced Congestion: No queues at toll plazas.
• Fewer Disputes: Transparent billing via centralized tracking.
• Boost to EV and Smart Vehicle Integration: Compatible with smart dashboards and fleet tracking systems.
• Increased Revenue Efficiency: Plug revenue leaks due to misreads or tag misuse.

Potential Challenges and Concerns

While GNSS offers many benefits, it comes with some concerns:

• High initial cost of setup for users.
• Privacy concerns related to vehicle tracking.
• Device maintenance and calibration may be needed.
• Coverage gaps in remote areas without strong satellite signals.

The government plans to address these through subsidized OBUs, awareness campaigns, and improved infrastructure.

India’s transition to GNSS-based tolling marks a bold leap into future-ready highway infrastructure. From accurate toll deductions to time savings and smoother travel, this system holds the potential to transform the country’s road experience. While there will be an initial learning curve for users, the long-term gains in transparency, efficiency, and cost-effectiveness make GNSS a significant upgrade over the existing FASTag model.

Travelers are advised to stay informed, get their vehicles registered in time, and embrace the change as India steers towards a smarter transportation future.
