'''LEOPARD''' ('''Light intensity Experiment with On-orbit Positioning and satellite Ranging Demonstration''') is a [[nanosatellite]] developed by [[Kyushu Institute of Technology]] (Kyutech) and [[Nanyang Technological University]] (NTU), which will demonstrate multiple technologies including multispectral cameras to monitor horizon glow, and on board processing of one-way radio signals. Students from 17 countries developed the satellite.[{{cite conference |url=https://digitalcommons.usu.edu/smallsat/2025/RA-S2-2025/5/ |title=LEOPARD: Demonstrating CubeSat Technologies for Light Scattering Observations and Satellite Positioning in LEO for Future University-Based Lunar Missions |last1=Orger |first1=Necmi Cihan |last2=Schulz |first2=Victor Hugo |last3=Corodova-Alarcon |first3=Jose Rodrigo |last4=Abdalla |first4=Hanadi |last5=Esit |first5=Mehmet |last6=Kushimoto |first6=Makiko |last7=Aziz |first7=Sara |last8=Cho |first8=Mengu |last9=Pham Anh |first9=Minh |last10=Mindaro |first10=Hery Steven |last11=Ratatamanun |first11=Subsinchai |last12=Ochirsukh |first12=Enkhmend |last13=Etti-Balogun |first13=Husseinat |last14=Kubo |first14=Shota |last15=Kudakwashe |first15=Jeje |last16=Tena |first16=Thibaut |last17=Ndayishimiye |first17=Rafiki Yves |last18=Nakayama |first18=Daisuke |last19=Sanli |first19=Alper |last20=Nishinaga |first20=Konosuke |last21=Oboshi |first21=Akihiro |last22=Mujuni |first22=Edgar |last23=Nyamakondiwa |first23=Ramson Munyaradgi |last24=Polimey |first24=IM |last25=Hidaka |first25=Hiroto |last26=Masui |first26=Hirokazu |last27=Rosales |first27=Josue Reynel Galindo |date=10 August 2025 |publisher=[[Utah State University]] |book-title= |pages= |location=[[Logan, Utah]] |conference=39th Annual Small Satellite Conference |access-date=3 June 2025}}] The satellite's size is 10cm×10cm×30cm, or a 3U size [[CubeSat]].
