2 Executive summary
Marvelmind Indoor Navigation System is off-the-shelf indoor navigation system designed for providing
precise (+-2cm) location data to autonomous robots, vehicles (AGV) and copters. It can also be used for
tracking other objects, where the mobile beacon can be installed, for example, in virtual reality (VR)
systems, helmets for construction workers or miners, etc.
The navigation system is based on stationary ultrasonic beacons united by radio interface in license-free
band and modem. Location of a mobile beacon installed on a robot (vehicle, copter, human, VR) is
calculated based on the propagation delay of ultrasonic signal (Time-Of-Flight or TOF) to a set of stationary
ultrasonic beacons using trilateration.

Key capabilities:
Parameter Technical Specifications
Radio coverage to beacons Up to 400 with full size 165 mm antenna
Location update rate - 0.5-45Hz
- Can be set manually
- Depends on the distance between mobile and stationary beacons (shorter distance
–higher update rate)
- Depends on the number of mobile beacons (update rate for 25Hz for 1 mobile
beacon => 25Hz/2 for 2 mobile beacons and 25Hz/3 for 3 mobile beacons)
- Depends on the radio interface profile (500kbps vs. 38kbps)
- Slightly depends on the number of stationary beacons –not like for mobile beacons
Power supply
- External power supply only
microUSB
Weight Modem from Starter set:
- 16,32 grams (with housing)
Modem size Size: 35x35x10 mm (with 50mm antenna: 55x55x65mm)

3.1 Indoor GPS architecture
Marvelmind Indoor Navigation System provides high-precision (± 2 cm) indoor coordinates for
autonomous robots and systems (“indoor GPS”). Brief description of the key elements of the system is
given on scheme below:

3.2 Modem description
- The central controller of the system. It must be powered all
the time, when the Navigation System works. It is
recommended to use active USB hub for that purpose or
even a regular USB power supply for cellular phones. A
USB power bank can be used too
- Modem is also used to setup the system, monitor it,
interact with the Dashboard
- It can be placed anywhere within radio coverage to have
permanent radio connection with all beacons –usually in
the radius of up to 100 meters with antennas from Starter
Set
- The radio coverage can be further extended to a few
hundred meters by using lower bitrate of 38kbps and full-
size antennas (tested up to 400 m in ideal conditions)
- Proprietary radio protocol is used for communication and
synchronization

4 Setup software (Dashboard)
4.0.1 After charging all the boards download the latest stable software package from
http://www.marvelmind.com/#Download
4.0.2 Select the SW version of the portable or distribution and unzip
4.0.3 Run the Dashboard and update the SW for modem using Dashboard => Firmware =>
Choose the file => Program
4.0.4 If you see message in the Dashboard “Not found modem connection to computer through
USB”, usually, it means that the driver is not installed. To install the driver, download it with
link at top and run installation file” click on the link under, install the driver
4.0.5 Ensure that
(a) You are programming modem’s SW to modem and
(b) You are using SW for 4.9, if you have HW v4.9
(c) You have the SW from the same SW pack, i.e. the Dashboard SW and modem SW must
be from the same SW pack. Don’t mix SW releases

4.0.6 While modem is connected to the Dashboard, press DEFAULT button in the Dashboard to
upload the default settings. See the print screen below:
4.0.7 Press RESET button on your modem after programming
4.0.8 After programming devices with the latest software, modem and beacons are ready for use.
4.0.9 Connect the modem/router via USB to the Windows PC with the Dashboard installed.
4.0.10 Run the Dashboard
4.0.11 In the left corner of the Dashboard Modem shall appear connected
4.0.12 Wake up all beacons by clicking on the buttons in the Dashboard on the below panel
4.0.13 If modem is not active and is not powered, the beacons will go asleep automatically after 1
minute. The system may run for the frequency search, if it is you’re the very first waking up the
beacons. If doesn’t succeed with this step, disconnect the modem and connect that beacon
again via USB. Press the DEFAULT button in the Dashboard and Read all button to make
sure that the radio settings are really the default ones. You may compare the radio settings on
the modem and the radio settings on the beacon. They must be the same
10
4.0.14 Freeze the map by clicking the button.
4.0.15 After you froze the map of stationary beacons, wake up the mobile beacon. After it wakes up,
it will be traceable in 5-7 seconds
4.0.16 By now, the system must be fully operational
