# Problem

Locating a rocket after a launch can be difficult. When the rocket reaches apogee (peak height), it deploys parachutes and glides back to the ground, often landing several miles away from the launch site (check out this video from the Illinois Space Society). Some tracking solutions exist, such as altimeters and radio beacons, however they all suffer from similar issues of being clunky, unintuitive, or expensive. Radio beacons don’t send out their exact location, and are tracked by following the strength of their signal, which only gives the general direction of the beacon. Altimeters send out their exact location, but are costly ($380+) and often require a laptop to receive their position, which is inconvenient to carry during a search. A few handheld trackers exist, however they are costly ($475+), difficult to reconfigure, and unintuitive. Additionally, all of these solutions are limited to 1 device.

# Solution

We want to make a 2-part tracking system: A tracking beacon (referred to as a “puck” or “beacon”), and a handheld tracking device (referred to as “tracker”). The beacon will be placed inside the rocket, and will continuously transmit its coordinates. On the receiving end, the tracker will compare its own GPS location with the coordinates from the beacon. To make this intuitive, the tracker will display the direction (using an arrow on the screen), as well as the distance to the beacon.

# Solution Components

## Subsystem 1: Microcontroller Processor (both beacon and tracker)
This will house the codebase for this project. This will mainly be to display to the screen of the tracker and handle button inputs by the user.

## Subsystem 2: TRACKING SENSORS
This subsystem consists of all required sensors/peripherals required for acquiring the location and direction from the tracker to the beacon
- **GPS Module (both):** To get longitude and latitude values of both components
- **GPS Antenna (both):** For connecting to satellites.
- **Magnetometer(tracker):** For measuring the heading of the user.

## Subsystem 3: COMMUNICATION SYSTEM
The entire project depends on successful communication between the beacon(s) and the tracker. Therefore we will need the following components to set up an ability for the tracker to search out certain frequencies and for the beacon(s) to send out the same frequencies.
- **Transceiver (both):** Required generating signal between beacon and tracker
- **Antenna (both):** Mid-ranged antenna capable of transmitting/receiving signals between 3-5 miles. Can be replaced in future with better antennas.

## Subsystem 4: BATTERY AND POWER SUPPLY
Create a battery management system that supplies consistent 3.3V to the necessary sensors and MCU.
- **LiPo Batteries (tracker):** 3.7V. Compact, have long battery life, and are readily available.
- **Voltage Regulator (tracker):** Regulating voltage from battery pack to sensors/MCU (3.3V)
- **Battery Holder (tracker):** Holding batteries

## Subsystem 5: DATA DISPLAY
This will simply be the screen we use to display all needed information for the user to track their beacons using the tracker
- **E-Ink Display:** For displaying compass, frequency, and distance data

# Criterion For Success

- Primary Criterion: Demonstrate that the “Beacon” or “Puck” can be found by an end user being guided by the “Tracker”’s on-screen information

- Additional Criterion: Demonstrate the ability to change frequency at which the “Beacon” and “Tracker” Communicate

Our project is to be a reliable, robust, and intelligent irrigation controller for use in areas where reliable weather prediction, water supply, and power supply are not found.

Upon completion of the project, our device will be able to determine the moisture level of the soil, the water level in a water tank, and the temperature, humidity, insolation, and barometric pressure of the environment. It will perform some processing on the observed environmental factors to determine if rain can be expected soon, Comparing this knowledge to the dampness of the soil and the amount of water in reserves will either trigger a command to begin irrigation or maintain a command to not irrigate the fields. This device will allow farmers to make much more efficient use of precious water and also avoid dehydrating crops to death.

In developing nations, power is also of concern because it is not as readily available as power here in the United States. For that reason, our device will incorporate several amp-hours of energy storage in the form of rechargeable, maintenance-free, lead acid batteries. These batteries will charge while power is available from the grid and discharge when power is no longer available. This will allow for uninterrupted control of irrigation. When power is available from the grid, our device will be powered by the grid. At other times, the batteries will supply the required power.

The project is titled S.I.P. because it will reduce water wasted and will be very power efficient (by extremely conservative estimates, able to run for 70 hours without input from the grid), thus sipping on both power and water.

We welcome all questions and comments regarding our project in its current form.

Thank you all very much for you time and consideration!
