Father Of Mass Market GPS : Sanjai Kohli

You definitely might have used Google Maps, Whatsapp location sharing feature and any other location sharing mobile application, yeah definitely its a cool feature in smart phones and hence they are so called smart ? ūüôā

but there is a man behind these popular GPS enabled devices who made it , Sanjai Kohli an Indian who worked on Mass Market GPS system, he is called as Father Of Mass Market GPS.

US Defense and Work on GPS

Sanjai started working in aerospace companies after completing his masters in US, during that time he was assigned a task where he suppose to add intelligence in bombs dropped from planes, in 1980’s 90 % of the bombs hit the unintended targets, Sanjai worked on a guided GPS systems, He and his team successfully completed the assigned task and all the US military weapons used the technology.

in 1993 GPS was being used in Tokyo to navigate in Cars, but because of many issues they never use to work properly, Sanjai started working on it and to make it commercialize. He setup a company SiRF by seeing the great opportunities, they reinvented the signal processing physics to reduce the cost and size.and increase power, resulting in tens of thousands of dollars of signal processing/communication equipment to reside in a single silicon chip. The chip was 200 times more capable than those used in the Japanese cars and was available at a fraction of the cost.” with SiRF. And the rest as they say is history. By 2006, 80% of GPS devices ran on SiRF chips. At its peak SiRF had a market capitalization of $3 billion.

With his great work, Kohli has been short-listed for the European Inventor Award (to be announced on April 28) instituted by the European Patent Office and the European Commission.

Sanjay Kohli has two patents

1. Multipath processing for GPS receivers  http://www.google.co.in/patents/US20030165186

ABSTRACT
A GPS receiver system determines the presence of trackable signals at code delays less than the prompt delay being tracked for a particular signal and changes the prompt delay to correspond to the smallest code delay having a trackable signal. Trackable signals at large code delays are multipath signals and may be separately tracked to aid in dead reckoning. The trackable signals at code delays not adjacent to the current tracked prompt delay may be tracked in the same channel as the prompt delay so that all satellite channels are continuously evaluated for multipath signals being tracked or a non-satellite specific channel may be used to sequentially step through the satellite signals to evaluate multipath on a satellite by satellite basis.
2. GPS Car navigation System https://www.google.com/patents/US6041280
ABSTRACT
A GPS car navigation system derives GPS position update information from motion of the car along the actual track. Turns along the track are detected when they actually occur and are compared with the predicted turns so that the time and position at the actual turn can be used to update the then current GPS derived position of the vehicle. Updating position information with actual turn data improves the accuracy of GPS navigation especially during single satellite navigation.

5 Innovative Ideas on Internet Of Things(IOT)

  1. An eco system that helps to adopt your daily life as per the need.

    Assume that you are very busy person, who is handling a so many things every day, you are traveling daily several places, you are almost forgetting yourself.

You may forget to drink enough water, you may forget to nap for a while, you were continuously sitting in an air condition room and keeping yourself away from natural air and sun light, you are driving you car every day and might miss some important meetings due to traffic but you could have made it, if you go by your bike.

a) Assume that your shirt has a sensor which will sense your body temperature and collects data every minute. Based on the data collected your smart phone suggest you when to drink water and how much to drink.

Your vehicle air conditioning system automatically adjusts the temperature by considering your current body temperature.

How Longitude, Latitude and GPS location services works

How Longitude, Latitude and GPS location services works

This article is to understand the mathematics behind GPS location services, how exactly google maps calculates the distance, how basic mathematics being used behind the screen.

Before going directly to mathematical part of it, let us understand the theory part ūüôā . how it is possible to locate places on the planet earth and calculate the distance? Mathematics has changed the world and is the base for everything. We all know that earth is like sphere, its not exact sphere because earth is spinning on its axis and the equator is flat compared to poles of the earth.

earth as sphere

earthLongitudeLatitude

Earth Longitude Latitude

The image above clearly shows how exactly the earth is, since its flat along the equator the radius at equator is more compared to radius along the poles.

But considering the mean radius of earth we shall assume earth as a perfect sphere. So the radius of the earth is 6371Kms.

Let us consider two locations JP Nagar, and Jayanagar in Bangalore India. If I locate these places on the sphere It looks as below.

There are many methods to calculate the distance between two points, many will prefer the below logic. Note here the first image show all Latitude values vary between [-90,+90] and longitude varies between [-180,+180]

Calculating Distance between two locations using Longitude and Latitude

                 
                //Earth radius is 
                static final double earthRadius = 6371; //Kilometers
                double dLat = Math.toRadians(lat2 - lat1);
		double dLng = Math.toRadians(lng2 - lng1);
		double sindLat = Math.sin(dLat / 2);
		double sindLng = Math.sin(dLng / 2);
		double a = Math.pow(sindLat, 2)
				+ Math.pow(sindLng, 2) * Math.cos(Math.toRadians(lat1)) *  Math.cos(Math.toRadians(lat2));
		double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));
		double dist = earthRadius * c;

		return dist;

The above code gives you the distance between two locations on a sphere.

How Project Look works ?

Google’s Balloon flys 20km above the earth surface¬†in the stratosphere, stratosphere is the second layer of the earth surface. Winds in this surface are stratified, balloon uses an intelligent algorithms which decides the direction and speed of the balloon, considering wind speed in stratosphere.

Google Loon’s Balloon Design

Loon’s balloon envelopes are made from sheets of polyethylene plastic, and they measure fifteen meters wide by twelve meters tall when fully inflated. When a balloon is ready to be taken out of service, gas is released from the envelope to bring the balloon down to Earth in a controlled descent.

This effort is important because 10% of the world’s population lives in areas without existing internet infrastructure. To affordably connect everyone, we need to build completely new technologies.

How Facebook’s Aquila Aircraft establish Connection ?¬†

Establishing connectivity using aircraft is a totally different idea, looks like practically impossible, proving theoretically might be easier but the real world scenario might be more challenging. using lasers might seem like science fiction. But science fiction is often just science before its time. It will be tested in the real world and continue refining.
