A Portable Transit Satellite Simulator

Offshore Technology Conference, 1978
ABSTRACT The portable TRANSIT satellite simulator described in this paper can test entire satellite receiver computer systems, from antenna input to the resulting computed fix, simulating any location in the world.

Intralesional therapy for in-transit and satellite metastases in melanoma.

Surgical Oncology Clinics of North America, 2015
Intratumoral therapy with bacteria/bacterial products dates to at least the 1890s. Over the decades this has expanded beyond the use of microbes and microbial products to include chemicals, cancer chemotherapeutic agents, cytokines, recombinant organisms, and hybrid molecules.

Saw Oscillator in UHF Transit Satellite Links

IEEE Transactions on Microwave Theory and Techniques, 1981
A 375-MHz surface-acoustic-wave (SAW) resonator controlled oscillator was developed for application in the Transit satellite marine navigation system. The SAW oscillator, in a 2-in/sup 3/ hybrid package, contains a heater, voltage regulator, and divider and is a direct replacement for a bulk wave oscillator and its multiplier chain.

Worldwide synchronization using the TRANSIT satellite system

Proceedings of the IEEE, 1972
American TRANSIT satellites have permitted improvements in the synchronization of satellite control networks. A prototype model for the decoding of time signals has been built and tested in the station of Bretigny Centre National d'Etudes Spatiales (CNES).

SAW Oscillators In UHF Transit Satellite Links

MTT-S International Microwave Symposium Digest, 1981
A 375 MHz SAW resonator controlled oscillator is developed for application in the transit satellite marine navigation system. The SAW oscillator, in a two-cubic-inch hybrid package, contains a heater, voltage regulator and divider and is a direct replacement for a bulk wave oscillator and its multiplier chain.

Resonant satellite transitions in argon [PDF]

Physica Scripta, 1990
The production of specific Ar+ satellite states has been studied with synchrotron radiation at wavelengths between 300 and 350 A with an effective energy resolution of 20 meV. The specific states studied were the (3P)4p(2P3/2), (1D)4p(2F7/2), and (1D)4p(2P1/2) states.

Satellite and In-Transit Metastatic Disease in Melanoma Skin Cancer: A Retrospective Review of Disease Presentation, Treatment, and Outcomes

Dermatologic Surgery, 2019
BACKGROUND Satellitosis and in-transit metastases (SITM) are uncommon in cutaneous melanoma and are associated with poor prognosis. However, the disease- and treatment-specific variables that predict outcomes among patients with SITM are poorly defined ...

The efficacy of immunotherapy for in-transit metastases of melanoma: an analysis of randomized controlled trials

Melanoma research, 2021
Nearly 10% of patients with high-risk early-stage melanoma will develop satellite or in-transit metastases (ITM), classified as stage III disease similar to lymph node metastases. The pivotal registration trials of the CTLA-4 antibody ipilimumab, and the

Observations of transitions in satellite scintillation

Journal of Atmospheric and Terrestrial Physics, 1968
Abstract A sub-auroral region of ionospheric irregularities with a well-defined equatorward boundary produces sharp transitions in the scintillation observed on VHF signals from the beacon satellite BE-B recorded at three New Zealand stations. Triangulation shows that the irregularities are located at heights between 240 km and 600 km, with about ...

Navigation using Carrier Doppler Shift from a LEO Constellation: TRANSIT on Steroids

Proceedings of the 33rd International Technical Meeting of the Satellite Division of The Institute of Navigation (ION GNSS+ 2020), 2020
A new global navigation system concept is studied that relies entirely on carrier Doppler shift measurements from the downlink signals of a large LEO constellation.
