How extending the kinematic model affects path following in off-road terrain for differential drive UGVs
(2022-05-31)
Traversal in off-road conditions for Unmanned Ground Vehicles is highly relevant for defence applications, with an increasing amount of research being put into the field. A central part of the autonomous traversal is path ...
Military Muscle-Flexing as Interstate Communication: Russian NOTAM Warnings off the Coast of Norway, 2015–2021
(2022-06-14)
When, where, and why does Russia issue warnings about missile launches and other potentially dangerous military activities in international waters and airspace west and north of Norway? Drawing on information derived from ...
Segmentation of PMSE data using random forests
(2022-06-22)
EISCAT VHF radar data are used for observing, monitoring, and understanding Earth’s upper atmosphere. This paper presents an approach to segment Polar Mesospheric Summer Echoes (PMSE) from datasets obtained from EISCAT VHF ...
Population Based Routing in LEO Satellite Networks
(2022-06-26)
Packet switching in a Low Earth Orbit (LEO) satellite network may calculate the best traffic route through the less populated areas of the planet, in order to avoid relaying through the busiest satellites. A number of ideas ...
Cooperative Caching in Space Information Networks
(2022-05-22)
Members of a Low Earth Orbit (LEO) satellite group need to coordinate their activities in order to improve the quality and timeliness of the services provided to terrestrial clients. As a report from a work in progress, ...
Geografisk mobilitet blant militært personell – en spørreundersøkelse om betalingsvillighet for pendling og flytting
(2022-08-31)
Norsk sikkerhets- og forsvarspolitikk har som mål å håndheve norsk suverenitet, sikre den territorielle integriteten og beskytte myndigheter og samfunn. Med stormakten Russland som nabo i nord, lang kyst og store havområder, ...
Kompetansebehov i Forsvaret knyttet til fremtidige teknologier – intervjuer med FFIs teknologimiljøer
(2022-06-30)
I denne rapporten beskriver vi en studie vi har gjennomført i FFI-prosjektet «Personellstudier» i samarbeid med Cyberingeniørskolen. I studien har vi intervjuet en rekke forskere ved FFI som jobber med fremtidige teknologier. ...
Overvåking av tungmetallforurensning ved Forsvarets destruksjonsanlegg for ammunisjon i Lærdal kommune –resultater for 2021
(2022-08-18)
I henhold til avtale med Forsvarets logistikkorganisasjon (FLO) foretar Forsvarets forskningsinstitutt (FFI) kjemisk analyse og vurdering av overvåkningsprøver som blir tatt ved Forsvarets destruksjonsanlegg for ammunisjon ...
Correlations between sound speed and density in seabed sediment cores collected in Norwegian waters
(2022-08-08)
In modelling of underwater sound propagation, knowledge about the seabed’s acoustic properties is essential, especially sound speed and density. These two properties are highly correlated, and standard empirical regressions ...
Challenges of Labelling Unknown Seabed Munition Dumpsites from Acoustic and Optical Surveys: A Case Study at Skagerrak
(2022-05-31)
The disposal of unexploded ordnance (UXOs) at sea is a global problem. The mapping and remediation of historic UXOs can be assisted by autonomous underwater vehicles (AUVs) carrying sensor payloads such as synthetic aperture ...
