Product Description: A study was performed on two measurement systems used to obtain profiles of refraction from a ship; the radiosonde and the rocketsonde. Refractive conditions measured by the Marwin Rawinsonde Set (MRS) utilizing radiosondes launched from U.S. Navy ships can yield misleading modified refractivity (M) versus height profiles. MRS obtained M unit profiles, when incorporated in propagation loss models such as Radio Physical Optics (RPO), also may produce unrepresentative propagation loss assessments. Rocketsonde obtained environmental parameters (temperature, relative humidity, pressure) are measured away from the ships influence. The ship can modify the environmental parameters and affect temperatures by as much as 3 deg C. Rocketsonde obtained data yield improved fine scale vertical resolution. Resolution approaching 5m obtained via rocketsondes is found to most closely resemble the actual environment. Rocketsonde data is available down to the near surface whereas there is a distinct lack of data from the surface to the launch point when utilizing balloon launched radiosondes. Inaccuracies in initial surface data drastically impact refractive profiles. Rocketsondes can be used regardless of sea state or wind conditions onboard ship and require no specific ship maneuvering to safely launch. It is found that the rocketsonde can obtain the requisite environmental parameters for refractive assessment on demand in less than half the time required to prepare and launch a balloon guided radiosonde.

FAQ'S

1. How do textbook rentals work?
It’s simple. Begin by searching for your textbook by ISBN (10 or 13-digit number that can be found on the back cover of each book), title, author or keyword. Next select how long you would like to rent the book then add it to your cart. Repeat for each book you’re looking for. After completing the order we’ll ship them to you and you’ll also receive a prepaid mailer. Return your books in the mailer by your rental due date.
2. Is renting a textbook better than purchasing it?
We offer both! You can buy or rent the book through Campus Book Rentals. It’s up to you to decide which option best meets your educational needs.
3. How do I track my order?
Login to your account here, you’ll see your current rentals listed textbook rentals listed with a yellow box that says “track”. Click the box to view the tracking number. *Not all books will have a tracking number since they may be sent from one of our partners. Tracking numbers will be updated as they become available.
4. How do I return my books?
When you rent textbooks from Campus Book Rentals you’ll receive a prepaid mailer. When it’s nearing your due date you’ll place your books inside the mailer and take it to the nearest USPS drop box or Post Office. If you don’t receive a mailer you can print a return label from your account. Return shipping is prepaid so please use either of the two methods to ensure they arrive at the correct facility.
5. Can I write or highlight in my book?
Of course! Just remember that future students will rent the same book after you, so please be respectful.
6. How much money can renting my books save?
It depends on the book. Generally renting textbooks can save you up to 80% compared to a new textbook.
7. Are Campus Book Rentals’ books the same as my bookstore’s?
Yes! We only ship US edition textbooks, which are the same as your campus bookstore.
8. Do access codes or other supplements come with a textbook rental?
One time use access codes and other supplemental materials are NOT included with rental books and must be purchased separately.
9. What if I don’t return my rental?
If your book rental is not returned by the due date, your credit card will be charged a non-return fee, equal to the replacement value for the book.
10. Can I purchase my book after I rent it?
Certainty! You’re only charged the difference between what you already paid and the value of the book at the time you initially rented. Login to your account and choose to purchase your book and it’ll walk you through the checkout process.
