How Accurate is Ship Location Data on MarineRadar?

When tracking a ship on any ship-tracking platform, the first question is whether the ship location data is accurate. We always take nearly accurate data at face value. When we open MarineRadar, we see many ships. When you open MarineRadar, you see ships moving on a map.
In this guide, you’ll learn how ship location data works, what makes it accurate, and why it may look wrong.
How Does MarineRadar Get Ship Location Data?
Before talking about accuracy, we need to understand how the data comes in. Ship data is accurate because it combines many technologies.
The technologies used for providing data are listed below.
1. Ships Use GPS
Every ship has a GPS (Global Positioning System).
This helps the ship know:
- exact location
- route
- speed
GPS is usually very accurate (within a few meters)
2. Ships Send AIS Signals
Ships send their GPS data using:
AIS (Automatic Identification System)
This includes the ship’s position, speed, direction, and name
3. Signals Are Collected
These signals are received by:
- Coastal towers (near land)
- Satellites (in the deep sea)
4. MarineRadar Displays the Data
Finally, MarineRadar:
- Processes the data
- Updates positions
- Shows ships on your screen
The global use of GPS for maritime navigation is supported by standards from the International Maritime Organization, which regulates modern navigation systems used on ships.
Factors That Affect Ship Location Accuracy
Although many technologies help improve data accuracy, some factors affect ship location accuracy.
Let’s break them down one by one.
1. Distance from Land
The ship’s distance from the land is the biggest factor.
Near Coastal Areas:
- Strong signals
- Fast updates
- High accuracy
In Deep Sea:
- Satellite tracking
- Slower updates
- Slight delay
So, ships near land are more accurate than ships in the middle of the ocean.
2. Update Frequency
Ships don’t update every second.
- Fast-moving ships → update more often.
- Slow ships → update less often.
As a result, there may be a tiny discrepancy between the actual and shown positions.
3. Internet Speed on Your Device
Sometimes the issue isn’t the ship; it’s your connection.
- Slow internet → delayed loading
- Weak signal → map lag
Ships may appear stuck or incorrect as a result.
4. AIS Signal Strength
AIS signals can be affected by distance, weather, and obstacles
Weak signals = less accurate tracking
5. Satellite Coverage
In the deep sea, satellites collect data, but not continuously. This causes slight delays in updates
6. Ship Behaviour
Some ships:
- Turn off AIS
- Send incorrect data
- Update slowly
This affects accuracy, too
Real-Life Accuracy Examples
Let’s make it super easy to understand.
Example 1: Ship Near Port
- Updates every few seconds
- Strong signal
- Very accurate
You see smooth movement on the map
Example 2: Ship in Deep Ocean
- Updates every few minutes
- Satellite-based
- Slight delay
A ship may jump on the map
Example 3: Ship with AIS Off
- No signal
- No updates
The ship disappears completely
Why Do Ships Sometimes Look Incorrect?
Sometimes the ship data may appear incorrect.
But here’s what really happens:
1. Data Delay
The ship moved, but the update hasn’t arrived yet.
2. Map Refresh Issue
Your app hasn’t refreshed properly.
3. Signal Loss
The AIS signal was weak or lost.
4. Zoom Level
At low zoom levels, positions may appear slightly off.
Free vs. Subscription: Does It Affect Accuracy?
MarineRadar is available in both free and subscription versions. The free version provides basic features, while advanced features are available through a subscription. There may be slight differences in the data received due to the features and benefits.
Free Version:
- Slight delay in updates
- Basic tracking
Subscription Version:
- Faster updates
- More real-time data
So, a subscription improves speed, which in turn improves perceived accuracy.
How Accurate is MarineRadar Compared to Actuality?
Let’s give a simple rating:
Area | Accuracy Level |
Coastal Areas | ⭐⭐⭐⭐⭐(Very High) |
Near Ports | ⭐⭐⭐⭐⭐(Excellent) |
Open Sea | ⭐⭐⭐⭐(Good) |
Remote Ocean | ⭐⭐⭐(Moderate) |
Tips to Get the Most Accurate Tracking
Here are easy tips:
1. Use a strong Internet connection
Better connection = faster updates
2. Zoom Into the Map
A closer view equals better clarity
3. Use Subscription (Optional)
Gives faster data updates
4. Track Ships Near Coastal Areas
More accurate results
5. Refresh the app.
Fixes delay issues quickly.
Why is MarineRadar reliable?
Even with small limits, MarineRadar is very reliable because
- Uses real AIS data
- Combines satellite + coastal tracking
- Updates continuously
- Covers global ships
That’s why it is trusted by:
- Marine professionals
- Businesses
- Ship enthusiasts

FAQs
Q: Is MarineRadar ship tracking accurate?
Yes, it is highly accurate, especially near coastal areas with strong AIS signals.
Q: Why is the ship location sometimes delayed?
Delays happen due to satellite tracking, signal gaps, or slow updates.
Q: Does internet speed affect accuracy?
Yes, slow internet can delay updates and make tracking look inaccurate.
Q: Are all ships shown correctly?
Most are, but some ships may turn off AIS or send limited data.
Q: Is the subscription more accurate than the free version?
It provides faster updates, which improves real-time accuracy.
