CHAPTER 4: SENSORS SENSOR TYPE DETAILS Once you have navigated to the Sensor detail screen, you will notice each sensor type has some attributes that are shared and some that are unique to the sensor. Below are the detail screens for the various sensors supported.
CHAPTER 4: SENSORS CALIBRATION, AUTO and MANUAL ZERO There are many environmental factors that can affect the accuracy of a power meter. Temperature, humidity, and circuit resistance are part of the measurement, but none of them remain constant while riding. A power meter must account for those changes to remain accurate. Auto-zero recalibrates the power meter over and over during a ride to keep the measurements from drifting.
CHAPTER 4: SENSORS CALIBRATION, PowerBeam Once you are paired with the PowerBeam there are two options available to calibrate the device: Rolldown calibration or Manual Calibration. There is also an option to reset the most recent calibration back to the factory default values. 9:34A 9:34A RU Sensor Activate Sensor Start Pairing Name RU1 Sensor ID 130 Delete Sensor Calibrate RU Calibration Roll Down Manual Reset to Default 9:34A RU Roll Down mph 0.
CHAPTER 5: NAVIGATION NAVIGATION OVERVIEW The Navigation section of the Joule GPS menu allows you work with a variety of features including Waypoints, Routes, Compass calibration, etc. Waypoints assist with remembering and navigating to a particular location. Routes allow you to follow a particular predefined path. Waypoints can be created directly on the Joule GPS and stored on the Joule or in the PowerTap PowerAgent software application (available on both Mac and PC).
CHAPTER 5: NAVIGATION WAYPOINTS For the purposes of the Joule GPS, waypoints are single specific locations on earth. Your home can be a waypoint. Your favorite trail head or cafe can be a waypoint. The Joule GPS can create, delete, select, and store waypoints. Each waypoint you create is stored on the device. Each waypoint is listed by its name, a distance and heading from your current location. A waypoint labeled “Start” is always in the list and represents the starting point of your ride.
CHAPTER 5: NAVIGATION WAYPOINTS, continued To navigate to a particular waypoint, select it from the list. At this point you can navigate to it, rename it or delete it. Selecting the Navigate To option will take you the GPS Map Dashboard. The name of the waypoint will be listed at the top of the screen along with the distance to the waypoint, from your current position, along a straight line, in the direction indicated by the heading arrow.
CHAPTER 5: NAVIGATION ROUTES Routes allow you to navigate an unfamiliar path. Routes also allow you to train using the pace of a previous ride as a measurement of your pace during the current ride, over the same course. Routes can be created from previous rides and copied onto the Joule GPS using the PowerTap PowerAgent software. Routes can also be created using your favorite mapping web site, exported from the site, imported into PowerAgent and copied to the Joule GPS.
CHAPTER 5: NAVIGATION ROUTES, continued Select a Route to ride or delete from your list of routes. If the route you select to ride has associated Turn by Turn directions, a Route dashboard will appear in your list of dashboards. The Route dashboard will display the heading, the distance, and direction to the next map point. The route is also displayed on Map Dashboard.
CHAPTER 5: NAVIGATION GPS STATUS Information related to your GPS signal can be checked in the GPS Status area. Your GPS signal can be set to Active or Off. The current accuracy of your position is estimated in meters. Accuracy improves as the device locks onto more than 4 satellites.

Appendix D: GPS OVERVIEW Understanding GPS Signal Acquisition and Signal Strength Overview: The Global Positioning System, GPS, originally developed for military purposes, was deployed over the span of years beginning in the 1980s, completing deployment in 1995. Today the GPS system is primarily used for civilian applications.
Appendix D: GPS OVERVIEW Understanding GPS, continued canyons. It can be hard to receive a satellite signal when not much sky is visible. Similarly, in urban areas, tall buildings, sometimes referred to as urban canyons, can cut down on the amount of viewable sky. Also, in rural areas, where the receiver may be under tree-lined roads or trails, the density of the tree canopy could have an effect on the GPS signal.
Appendix D: GPS OVERVIEW Understanding GPS, continued A receiver will need to lock on a minimum of 4 satellites to get an initial good position location. In order to find other satellites the receiver will reference a copy of a data file, containing position data of all other satellites in the system. This file is commonly referred to as the almanac file. Each satellite is in constant communication with the other satellites in the system.
