Position Location And Navigation (PLAN) Group
Welcome to our new web site. An archived version of our previous site is available here.
The Position, Location And Navigation (PLAN) Group is dedicated to the research, development and improvement of wireless positioning and navigation technologies for outdoor and indoor use. To this end, most of our work is encompassed in the following research areas:
GNSS Signal Processing
- Signal acquisition and tracking algorithm development, including high accuracy
- Multi-frequency, multi-systems signal processing enhancements
- Impact of signal attenuation and High Sensitivity GNSS, including Assisted GNSS (AGNSS)
- Tight and ultra-tight integration of GNSS with inertial and other sensors
- Impact of oscillators on signal integration
- Multi-sensor augmentation
- Ground based RF ranging systems and augmentation
- Software GNSS receiver development
- Centimetre-level accuracy positioning and multi-frequency ambiguity resolution
- Velocity and attitude determination
- Atmospheric propagation effects
- Indoor, pedestrian and vehicular navigation

Congratulations to Dongyu Zhang
Dongyu Zhang successfully defended her MSc. thesis “Ultra-Wideband Ranging for In-Vehicle Smartphone Positioning” on Zoom this afternoon. She will be returning to China next week and will complete her corrections while quarantining. Her thesis should be posted on the new group website in May. I hope we can take her out for lunch on a future visit to Calgary.

Congratulations to Maliha Monsur
Maliha Monsur successfully defended her MASc thesis “GPS/WiFi Integration for challenging environments using raw GNSS data” at UBC Okanagan this afternoon. Maliha was co-supervised by Kyle O’Keefe and Richard Klukas and spent one term of her master’s program in Calgary in 2018. She has recently moved from Kelowna to Vancouver and we wish her luck in her future endeavors.

Congratulations to Cheng Huang
Cheng Huang successfully defended his MSc thesis “Wheel Odometry Aided Visual-Inertial Odometry in Winter Urban Environments.” He has some minor corrections do by the end of the month and then his thesis will be the first to be posted on the new PLAN group website. Cheng joined the group in September 2018 and his work was partially supported by Dr. Gérard Lachapelle’s iCORE Chair in Wireless Location. Cheng has already started an internship with Leica in Calgary.

Congratulations to Sharareh Asal Nagdhi
Asal Nagdhi successfully defended her PhD this morning on a Zoom meeting. She has some minor revisions to complete in the next three weeks and hopefully, eventually, we can take her and the group for lunch at the Grad Lounge to celebrate. She joined the PLAN group in July 2016 and we have enjoyed working with her for the last 4 years. Her thesis: Improving Bluetooth-based Indoor Positioning Using Vision and Artificial Networks, will be posted on the group website in mid-July.
