Understand how PanX Positioning Works Compared to GPS
How PanX Works
An overview of how our technology works and how it differs from normal GPS.
The core differences between PanX Positioning System (PPS) and Global Positioning System (GPS) is that PPS uses a ground-based network of hundreds of powerful transmitters, and GPS uses a satellite-based network of 24 satellites armed with weak transmitters.
First, Let’s Discuss GPS
Before understanding why PanX Positioning is so important, we must first truly understand GPS.
GPS was invented and the first satellites launched almost 40 years ago. Technology has evolved 100 fold since then, but we still rely on 35 year old equipment, “maintained” by the dying NASA program.
Some of the most powerful infrastructure in North America relies on this outdated technology.
Satellites travel at 65,000 mph around the earth and are 1,200 miles above us. The amount of power they have to send a signal down to earth is about the same as your cell phone. When the signals arrive, they are so weak, that the smallest interference (like the wall of a building) can destroy it.
GPS was a great invention for its’ time. However, even with great coverage, GPS is useless to americans who spend 70% of their time indoors where GPS signals can not reach.
Since the satellites are so weak, our GPS enabled devices must do most of the heavy lifting. This puts strains on the battery and restrict us from minimizing its’ size.
GPS signals are too weak to ever be usable indoors, or even in thick cloud or foliage cover. This restricts the amount of applications GPS is usable for.
How Does PanX Positioning Solve this?
Because of GPS’s restrictions, we set out to solve these problems.
PanX Positioning System (PPS) wanted to fix a series of specific problems that GPS has, in order to offer a location technology like GPS to people and businesses that need this service indoors, where GPS normally would not work.
- Ability to work indoors
- Impossible to Jam
- Speed up acquisition time
- Decrease battery consumption
- Easily upgradable system over time, as technology develops
1. Ground-Based Network
After much deliberation, we settled on a ground-based network utilizing existing AM/FM signals. These signals are perfect since AM was originally designed specifically for deep penetration within buildings.
- Signal Strength
- A GPS satellite can only gain power from small solar reflectors. This means that the max power a GPS satellite can function on is less than 50 watts. In comparison its less than 1 lightbulb uses in your house. In contrast our radio stations can use half a million watts to send very strong signals that will go deep within buildings and even underground!
- Not only do these ground based signals have a reputation for reliability, but if anything goes wrong its much easier to send a technician out to a tower than to send a man into space to fix a satellite.
- Coverage across the US has already been secured with operating agreements of existing tower operators. One tower can have an incredible range of more than 100 miles. And because we operate above the frequency of audio, our signals can be received even in locations that you would not get audio radio (such as the top of a mountain).

2. Portable Device
Most of the work happens at the tower, so our devices can be smaller, cheaper, and more battery efficient
One major difference between PPS and GPS is that with PPS we have most of the calculations happening at the tower. This saves battery life and reduces bulk because the real computing power isn’t happening on the device. This enables us to make it smaller and fit into new places that GPS devices could have never fit before.
We can fit the receiving device into the frame of a bike or between two layers of fabric. Unlike the bulky battery hogging GPS devices of today.
3. Limitless Potential
Now that GPS has been re-invented we can throw out our previous notions of location tracking and start thinking about the new possibilities that this allows us to pursue.
Here is a list of new ways that this technology is being implemented or plans to do so have been discussed. None of these would have been doable with current GPS technology. An alternative was needed, PanX Positioning System was the answer.
Hotels were the original reason that PanX was started. In the journey to help protect the hotels, we discovered and invented PPS. Hotels are still at our core, and we have validated with several hotels and preparing for beta tests in hotels by the end of Summer 2013.
Hospital buildings’ thick walls and deep interiors are a nightmare for cell phone signals, and even worse for GPS devices. In conjunction with one of our partner’s software, PanX can offer increased customer satisfaction, increased problem response time, and decreased hospital liability.
The tragedy of the Newtown shootings brought awareness to school districts that better protection needs to be provided to teachers. Several school districts have stepped forward to give PanX devices to teachers increase response time to children in emergencies.
A more creative use of PanX technology is to install it in the frame of a luxury bike. The manufacturer can offer built-in GPS as a feature, where users can see their speed, route, and other valuable data from a computer or smartphone after the trip.
Mobile Devices like smartphones, tablets, and laptops are already trying to incorporate GPS technology. Many are required to because of the E911 mandate. However, it has been difficult to achieve true GPS signals since these devices are normally used indoors. Most current devices use aGPS which is a system that tries to GUESS your location based on cell phone and wifi towers seen nearby. Wouldn’t a true accurate location be so much better?
