Positioning with
Ultra Wide Band

Hans Forsberg
Smallest
Ultra Wide Band (UWB):
About me:
Hans Forsberg
Sensor & robotics expert
Positioning @ cm accuracy:
GPS, RTK-GPS
WiFi
BLuetooth
ZigBee
SLAM, VIO
Inertial
HW, Beacons
Laser
etc...
Spark/Gap radio:
UWB as low cost-chip
"I do not think that the wireless waves I have discovered will have any practical application"

Henrich Rudolf Hertz
ToF-Ranging
Highspeed communication
Mesh networks
Low cost
Low Power
Secure
Good range, LOS,NLOS, multipath
Ultra Wide Band (UWB):
UWB Implementation:
Ranging schemes:

Two-way ranging
Sym two way ranging:
Decawave
DWM1000
BeSpoon
IR-UWB
Error handling:
Our research setup:
'Obvious' applications:
Future?

First generation, what to come?
C, Best 'constant' available ?
Clock and timing ? Shared clock ?
Leading Edge Detection
Compare RTK-GPS, PRN, GoldCodes..
Model-building, Filtering
Into the Future:
What application?
Robotic arms ?
Key enabler for autonomous systems
Micro location for IoT.
Indoor positioning
Surveillance
...
Thank You!
