Using a GPS to navigate around town has become so commonplace that it’s actually making the average person worse at following directions on their own. This is a minor sacrifice to make, though, with the amount of utility GPS provides.

Despite the widespread use of this technology, not many people fully understand how it functions. And, the answer is likely more interesting than you think.

Not sure where to start? Don’t worry, weโ€™ve got you covered.

Let’s take a look at everything you need to know about satellite navigation

Global Positioning System (GPS)

The above term refers to a network of satellites (approximately 30 of them) that orbit approximately 20,000 kilometers above Earth. These satellites were originally designed for military use, but today they allow anyone with a GPS device to navigate freely.

Multiple satellites work together in order to pinpoint your current position and determine how far away you are from your intended destination. The process utilized in this scenario is known as trilateration.

What Exactly Is Trilaterartion?

You can better understand this process by imagining that there are three satellites orbiting far above your position. Each of these satellites has an imaginary ‘sphere’ that surrounds it and overlaps with the spheres of others.

For clarity, we’ll refer to these satellites as S1, S2, and S3.

Your GPS device will send a signal to S1, S2, and S3 in order to determine your distance from each of them. Then, your device will use trilateration to determine where the imaginary spheres intersect to determine your current position.

Since this interaction happens at the speed of light, you’re able to get a highly accurate reading even while traveling at high speeds. Additionally, the more satellites your GPS device is able to interact with, the more accurate your reading will be.

What Else Can GPS Be Used For?

Surprisingly, GPS technology can help monitor natural disasters.

Data about volcanoes, tsunamis, and earthquakes can be gathered from GPS devices during, before, or after a disaster.

GPS is also highly useful when land surveying. This includes mapping out sea floors, measuring the size and shape of structures, and gathering data about an area within a particular region.

An entire country, for example, could be surveyed by GPS relatively easily due to the country’s borders being used as parameters for the measurement.

As previously mentioned, GPS has plenty of military applications, including protecting soldiers and managing resources.

A common scenario is to pinpoint and monitor the position of a specific group of enemy combatants or to monitor the position of the military’s own soldiers.

Understanding Satellite Navigation Can Seem Difficult

But it doesn’t have to be.

With the above information about satellite navigation in mind, you’ll be well on your way toward making the most of this technology.

How NEOFECT Created a Smart Glove (Robotic Arm) That Uses Online Gaming for Rehabilitation

Wearable technology keeps evolving. And it is transforming the way we experience the world. Watches, eyeglasses, rings, bracelets and even smart home devices like the thermostat are changing how we consumer information, monitor our health and use home products. Smart technology has a significant role to play in how people will live in the future.

NEOFECT wants to change how to aid rehabilitation and the provision of clinicial real-time patient data. In an interview with  Scott Kim, Neofect’s co-founder and CEO of the US office, he spoke to us about how he started NEOFECT, the company’s success factors and challenges they have faced in their bid to change physical therapy using online gaming.

Brief summary about your startup

Established in 2010, NEOFECT is a mobile health startup with a vision to deliver an affordable and effective at-home system to aid neuro patients with central nervous system disorders such as a stroke.

Its first product, RAPAEL Smart Glove, combines a wearable device, virtual reality and gamification for rehab exercise, while its software analyzes the data from built-in sensors and provides training tasks based on the patient’s activity level.

The device has been successfully employed by a number of major hospitals in South Korea since December of 2014, and approved for use in the US and Europe. NEOFECT has offices in S. Korea, San Francisco, and Poland.

Why and how it was started

The President of NEOFECT, Ho-Young Ban, experienced first-hand the difficulties faced by stroke patients and their families when his father and two uncles fell victims of stroke.

Although his uncles were fortunate to survive, they had to turn down the rehab therapy because of the costs involved. So, when his friend Young Choi came up with an idea of Rapael, Ban could not resist.

Soon after, their classmate from the University of Virginia’s Darden MBA program Scott Kim joined the team to launch the US operations.

Kim was born with spinal bifida and went through a surgery and a long rehabilitation process, so he immediately recognized the opportunity and became a co-founder and the CEO of the Neofect’s US office.

What has been the biggest success factors

Personal motivation of the founders combined with the latest, most advanced smart technologies have become the major engines behind the company’s success.

– Gamification, which motivates a patient throughout the rehab process. It helps to induce neuroplasticity for hand function of a patient with a brain damage.

Various rehab games are updated monthly and each game targets specific movements such as squeezing the orange for finger flexion/extension and pouring wine for forearm pronation/supination, for example.

– Artificial Intelligence: the software analyzes data from the glove’s sensors and provides training tasks based on the patient’s activity level. The algorithm is designed to enhance learning multiple functions by offering an optimal task at a proper level of difficulty.

– Wearable Device: RAPAEL Smart Glove is a wearable bio-feedback training gadget. Lightweight and designed to fit different hand sizes, it uses the Bluetooth technology to collect the patient’s data.

What are the biggest challenges you have faced launching and running the company?

The biggest challenge was the product’s concept itself. Many people believed that Rapael could be a threat to the therapists. Fortunately, after we launched the program in several hospitals, we’ve been able to prove that our device is designed with the doctors’ and patient’s needs in mind and helps them make the rehabilitation process more efficient.

Which do you think is most important: the right market, the right product, or the right team?

This sounds like a cliché, but the right team is easily the answer to me. With the right people, you can make necessary adjustments based on new information to make sure there is a product-market fit.

My previous job was to lead a team to make mobile apps – without any exception, all great apps loved by users were made by great teams.

Final words for those chasing the startup dream

Never underestimate the importance of execution. Many people waste their time just to validate what they think or others think, or even just to finish the conceptualization.

However, you should “fail fast” in order concentrate your efforts on building a product which has a market demand, and of course, to save time and money as well.

Plus, you should fail while you are small rather than big, if you’re meant to face it. The earlier you do the reality check, the faster you can reach your goal, although it might cost you a couple of failures at the beginning.
